The new TV season's finally here, but with so many shows competing for your precious tune-in time, flipping through the channels can feel more like a burden than a break. Don't let TV viewing turn into a chore! Instead, check out our 14-show list of fall TV's best bets. Some are new, some are returning, but all are worth a watch. In no particular order:
Series premiere: Thursday, September 24, 8pm
ABC
Cast: Joseph Fiennes, Sonya Walger, Dominic Monaghan, John Cho
When the entire world is given a glimpse into the future due to a mysterious black-out, each person sees a series of events in his or her life that would take place six months later. As people begin to piece together their visions and attempt to pinpoint the cause of this mysterious phenomenon, it leaves many people wondering whether their own destinies can be changed, and what affect those changes could have on others. With an ensemble cast like this, we're definitely looking forward to 'FlashForward'!
2. 'The Jay Leno Show'
Monday - Friday, 10pm
NBC
Cast: Jay Leno
Following the end of his 17-year tenure with 'The Tonight Show,' Jay Leno made his highly-hyped transition from late night to prime time on Monday, September 14; more than 18 million viewers tuned in to catch the debut. Though critics, in general, wrote it off as "snooze-inducing," Leno's new show was also instantly familiar -- and for many longtime viewers, that's not a bad thing: As well as introducing new comedy sketches in the weeks to come, fans can expect Jay to continue his comfortable, tried-and-true classics (Jaywalking, Headlines, etc.). Many of us wonder if this'll just be another 'Tonight,' but Leno says his new show will feature more variety-style elements.
Thursdays, 9:30pm
NBC
Cast: Joel McHale, Chevy Chase, Gillian Jacobs, Yvette Nicole Brown, Alison Brie
When fast-talkin' lawyer Jeff Winger (Joel McHale) finds his degree's been revoked, he ends up back in school at Greendale Community College surrounded by misfits. With help from his fellow classmates Pierce (Chevy Chase), Troy (Donald Glover), Shirley (Yvette Nicole Brown) and Annie (Alison Brie), Winger forms a Spanish study group (despite the fact that his command of the language is anything but good) in an effort to seduce classmate Britta (Gillian Jacobs). If you're a fan of Chevy Chase -- who plays a retired moist-towelette mogul -- and 'The Soup's' Joel McHale, this one's a must-see.
4. 'Grey's Anatomy'
Season premiere: Thursday, September 24, 9pm
ABC
Cast: Ellen Pompeo, Patrick Dempsey, Sandra Oh, Eric Dane, Katherine Heigl
'Grey's' had us bawling our eyes out all the way through last season's finale when we found out the severely mangled 'John Doe' was our beloved George O'Mally (T.R. Knight), and Izzie Stevens (Katherine Heigl) regained her memory after her brain surgery only to collapse again. Get ready to break out the tissue box: We suspect series creator Shonda Rhimes won't let us off the hook that easily in season 6; the premiere alone -- set to fill us in on the fates of George, Izzie and the rest of the Seattle Grace gang is likely to be a tear-jerker. With Knight's confirmed departure, Heigl's extended leave of absence and Pompeo's maternity leave, we're already expecting big changes; rumor has it the down economy's hit Seattle Grace, too, and we might even see some of our favorite docs let go. We are, however, very excited to find out what becomes of Christina and Owen's budding romance, and whether a marriage will finally play out for Meredith and Derek.

5. 'Cougar Town'
Series premiere: Wednesday, September 23, 9:30pm
ABC
Cast: Courteney Cox, Brian Van Holt, Dan Byrd, Christa Miller
Can a woman over a certain age be a mom, a successful career woman and still be on the prowl? In this new comedy, recently divorced single mother Jules Cobb (Courteney Cox) finds herself facing the realities of getting back in the dating game in her 40s -- except she has no game. With creator Bill Lawrence ('Spin City,' 'Scrubs') and executive producers/real-life husband-and-wife David Arquette and Courteney Cox at the helm, we're expecting good things from 'Cougar Town.'
6. '90210'
Tuesdays, 8pm
The CW
Cast: Rob Estes, Lori Loughlin, AnnaLynne McCord, Shenae Grimes, Jennie Garth
The former 'Beverly Hills 90210' got an edgier facelift last season with a shortened title, new characters and guest appearances by original cast members including Tori Spelling, Jennie Garth and Shannen Doherty. Now the CW revamp follows the lives of six West Beverly High School teens, in particular Annie and Dixon Mills, who recently moved from Kansas, and their struggles adjusting to life in the glitzy ZIP code. The first-season finale ended with explosive cliff-hangers that kept viewers wondering what was to become of Adrianna, who just gave birth at 16; Silver, who suffered from a bipolar breakdown; and Annie, who in the last scene, was involved in a messy hit-and-run accident. Needless to say, we can expect lots more teenage debauchery, and more breakdowns, in season 2.
Wednesdays, 9pm
Fox
Cast: Jane Lynch, Kevin McHale, Amber Riley,Chris Colfer, Jayma Mays
When the pilot episode of 'Glee' first aired back in May, responses were mixed: Some viewers and critics just didn't know what to make of a musical-comedy-drama revolving around the lives of the students in a Midwestern high-school glee club and their (mostly) clueless teachers. Four months later, there's still no easy explanation. Created in part by Ryan Murphy ('Nip/Tuck') and originally envisioned as a movie, 'Glee' manages to find quirkiness in stereotypical high-school characters (the Jock, the Nerd, the Cheerleader, etc.). The show's humor, too, is on the quirky/self-deprecating/edgy side. And while there are plenty of full-length musical numbers, don't mistake this for another 'High School Musical.' Songs range from show-tunes standards to classic-rock anthems to Rihanna chart-toppers. The only reason not to watch? It might hit too close to home.
8. 'Modern Family'
Series premiere: Wednesday, September 23, 9pm
ABC
Cast: Ed O'Neill, Jesse Tyler Ferguson, Julie Bowen, Sofia Vergara
'Modern Family' is a new mockumentary following the everyday lives of three modern-day American families, each with different backgrounds, as they are filmed for a reality-style TV series in The Netherlands. Jay (Ed O'Neill) is always mistaken to be the father of his much-younger second wife, while Jay's daughter Claire (Julie Bowen) and her husband Phil yearn for a more open relationship with their three kids, and Jay's openly gay son Mitchell (Jesse Tyler Ferguson) and his partner Cameron adopt a baby girl from Vietnam. With a cast -- and premise -- like this, we'll be surprised if 'Modern Family' doesn't become a big hit.
Series premiere: Monday, September 28, 9pm
NBC
Cast: Cliff Curtis, Derek Luke, Anastasia Griffith
'E.R.' meets 'Emergency' on this slick action-drama, which tracks a team of highly trained paramedics as they treat injury victims in the initial moments of tragedy. The show's ceaseless explosions, vehicle crashes, hovering helicopters, slo-mo editing and over-the-top background music and voiceovers at times make it feel more like a Michael Bay blockbuster than a weekly TV series. (And are these emergency medical procedures really covered in the EMT first-responders' training guide? That would explain why ambulance pick-ups are so expensive.) Realism aside, 'Trauma' could be just what the doctor ordered for adrenaline junkies in search of a new favorite show.
Tuesdays, 8pm
NBC
Cast / Trainers: 16 contestants; Jillian Michaels, Bob Harper
It's true that these two-hour episodes require a significant commitment, both in terms of time and the fact that first-hour action is pretty much limited to obese strangers working up a sweat. For its eighth season, though, 'Loser' is giving viewers another reason to tune in: It's upped not only contestants' excess bodyweight, but their emotional baggage, as well. The new season, which focuses again on singles rather than couples, is "all about second chances": One contestant, for example, lost her family in a tragic car accident and wants to start a new life; another is last season's heftiest 'Loser,' back to continue his weight-loss adventure. And perhaps most intriguing is Miss Shay Sorrells -- at 476 pounds, the heaviest 'TBL' contestant ever -- who's hoping to find "redemption from her dark past" via slim-down. All are competing for the show's $250,000 grand prize -- and, of course, the opportunity to be screamed at by Jillian on national TV.
11. 'The Forgotten'
Tuesdays, 10pm
ABC
Cast: Christian Slater, Heather Stephens, Tyler Davies
On this Jerry Bruckheimer-produced drama, a band of "citizen" detectives dedicates itself to cracking unsolved crimes: clue-less murders and missing-persons cases that law enforcement professionals gave up on years ago. But these amateur answer-seekers aren't doing this out of the goodness of their hearts. Each member of Chicago's so-called "Forgotten Network" has a personal reason for getting involved. (Christian Slater's character, Alex Donovan, for example, is an ex-cop whose life fell apart after his 11-year-old daughter's abduction.) Sound like your standard cold-case-of-the-week series? There's a twist: In a 'Lovely Bones' spin, every episode is narrated by its unseen victim, who watches over Alex & team as they cobble its path back from Limbo. Yes, 'The Forgotten' has issues: a penchant for melodrama (probably), cast shake-ups (already) and a lousy time slot (definitely), among others. But we like the concept, and we like Christian Slater. So damn the drawbacks (and critics) and give it a shot.
12. 'The Vampire Diaries'
Thursdays, 10pm
The CW
Cast: Ian Somerhalder, Candice Accola, Steven R. McQueen, Nina Dobrev
'The Vampire Diaries,' a television adaptation of L.J. Smith's 1991 horror trilogy, centers around 17-year-old Elena Gilbert, who falls in love with Stefan Salvatore, the strangely mysterious new boy at school. Little does Elena know that Stefan and his older brother Damon are at war for Elena's soul -- and for the souls of her family and friends. For 'Twilight' fans, this might just be the thing to hold you through the unbearable wait for 'New Moon.' And beside, what could possibly make for better TV than a love triangle between a high-school girl and two sexy vampire brothers?
13. 'Shark Tank'
Sundays, 9pm
ABC
Cast / 'The Sharks': Real-estate investor Barbara Corcoran, fashion mogul Daymond John, financial expert Kevin O'Leary, technology innovator Robert Herjavec, infomercial king Kevin Harrington
If you love a good shark week (and who doesn't?) this one's for you. Producer Mark Burnett -- who, thanks to successes including 'Survivor' and 'The Apprentice,' knows from savvy pitching -- is the man behind the remake of this popular British reality series, in which "inspired" entrepreneurs looking for funds to launch or expand their businesses present ideas to a panel of five deep-pocketed, would-be investor-judges. But here's the fun part: These "judges" not only approve or deny entrepreneurs' money requests, they also compete with one another to invest in the best/most potentially lucrative ideas -- and haggle with the pitching businessmen/women over what they'll get in return for footing the bills. As one might expect, ideas run the spectrum from boneheaded to brilliant.
14. 'V'
Series premiere: November 3, 8pm
ABC
Cast: Elizabeth Mitchell, Logan Huffman, Scott Wolf, Morena Baccarin
Everything eventually comes around again, especially '80s TV shows: Like NBC's then-groundbreaking sci-fi 1983 miniseries (and short-lived follow-up series), this "re-imagining" of 'V' tells the story of an alien civilization that comes to Earth in peace -- but not really. In the 2009 version, 'Lost' star Elizabeth Mitchell is FBI counter-terrorism agent Erica Evans, the first human to realize these alleged good-guy E.T.s in fact have pretty evil intentions. And news anchor Chad Decker (Scott Wolf) is dying to get an exclusive with the aliens' hottie leader, no matter what it takes. While you're waiting for the new 'V' to premiere, why not refresh your memory and watch the original again? You've probably still got the VHS tapes stashed away somewhere.
