Although this sci-fi drama from the brain of J.J. Abrams premiered to a healthy 10 million viewers, its audience dwindled each week. The finale drew a season-low 4.75 million viewers — not good enough for a second-season renewal.

Allen Gregory (Fox)
Not all Fox animated comedies are created equal. This one came from the the mind of Jonah Hill, who also voiced the show's pretentious 7-year-old title character. The only things more hateful than Allen were the reviews the show received. Maybe if Seth MacFarlane had written it?

Are You There, Chelsea? (NBC)
One of last development season's buzziest pilots fell absolutely flat. After being held until midseason, this Laura Prepon-fronted comedy, based on Chelsea Handler's book, Are You There Vodka? It's Me, Chelsea, drew fewer than 3 million viewers at its lowest point. No one would want to drink to those numbers.
4 of 34 Neil Jacobs/NBC
Despite an engaging premise, a beautifully emotional pilot and a standout performance by Jason Isaacs, audiences just didn't find this dual-reality cop drama arresting. The silver lining for creator Kyle Killen: This one lasted 11 more episodes more than Lone Star.

Best Friends Forever (NBC)
What? You didn't even know this show was even on the air? Neither did most people. After averaging less than 3 million viewers, NBC yanked it from the schedule.
6 of 34 Vivian Zink/NBC
It's too bad NBC didn't love this quirky rom-com starring Amanda Peet as much as critics did. The Peacock burned off its six-episode order with three weeks of back-to-back airings in late March.

Breaking In (Fox)
Deja vu? After being canceled last year, this Fox comedy was brought back from the dead this season, but even new cast member Megan Mullally couldn't save it. Maybe the third time's the charm? (No, Fox, we're just kidding.)

Charlie's Angels (ABC)
Despite the nostalgia factor and plenty of sex appeal, this reboot of the classic crime drama just didn't play the second time around. ABC shut down production after only four low-rated episodes aired. Sorry, Charlie.
9 of 34 Jordin Althaus/Warner Bros.
After surviving near-death multiple times, NBC gave this little spy drama that could a final 13-episode run to wrap things up. In the end, Sarah may not remember Chuck, but if she's half the fighter that Chuck was, we know those kids will eventually get their happy ending.

CSI: Miami (CBS)
After 10 seasons of solving crimes and taking off his shades, David Caruso's Horatio Caine was sent into retirement. Still a decent performer ratings-wise, CBS likely made this decision based on the bottom line. (The longer a show runs, the more costly it is to produce.) When you're the No. 1 network, you pretty much have a… license to kill. Yeeaaaahhhhhhh!!!!

Desperate Housewives (ABC)
After eight seasons of murder, betrayal and natural disasters, the ladies of Wisteria Lane finally moved on. Though the show ended with a far smaller audience than it had during its heyday, watching the finale did make us feel like we were losing old friends. And there's just something about creator Marc Cherry's "everybody has a secret" premise that will always make us wonder what's happening on TV's most famous street.

The Finder (Fox)
Although it grew out of Fox stalwart Bones, this Geoff Stults-fronted procedural just couldn't find an audience. Even with the post-American Idol timeslot, The Finder averaged around 6 million viewers before being banished to Friday nights and ultimately canceled.
13 of 34 Steve Wilkie/NBC
The Firm (NBC)
Even with beloved source material and a strong cast fronted by Josh Lucas, this update of John Grisham's breakout hit just didn't click with viewers. Suffering from bad reviews, it was the lowest-rated drama premiere ever for NBC and was quickly moved to Saturday nights.
14 of 34 NBC
Free Agents (NBC)
Borrowing comedy from the Brits worked with The Office, but not so much with this workplace romantic comedy starring Hank Azaria and Kathryn Hahn. The four episodes that aired before NBC yanked it off the schedule averaged 4.1 million viewers.

This midseason replacement was seen as the heir to Desperate Housewives' throne, perhaps to the show's detriment. The catty Christian ladies of Texas didn't strike the same nerve as the Housewives did, and the show's audience slid lower and lower as its season wore on.
16 of 34 Jojo Whilden/CBS
A Gifted Man (CBS)
In his first TV role, Patrick Wilson played a brilliant doctor who is regularly visited by his dead wife. Although the show was far from your typical medical drama, its Friday night timeslot failed to earn the show many viewers. CBS opted not to order a full season and wrapped the show's run after 16 episodes in March.
17 of 34 Colleen Hayes/NBC
Harry's Law (NBC)
This one's perhaps the most shocking. True, this Kathy Bates legal drama from David E. Kelley skewed very old (its demo rating average was a paltry 1.1), but with an average audience of 7.8 million viewers, it pulled in more eyeballs than any other NBC show.
18 of 34 Ray Mickshaw/Fox
After eight seasons of diagnoses that were hardly ever lupus, the doctor is out. Fox's onetime juggernaut shed quite a bit of its audience in its old age, but the creators crafted an emotional ending arc that once again highlighted House and Wilson's friendship, which was always the show's beating heart.
19 of 34 Fox
I Hate My Teenage Daughter (Fox)
There was plenty of hate to go around: This was one of the worst-reviewed shows of the season. After airing four low-rated episodes in the late fall of 2011, Fox held this Jaime Pressly-fronted comedy back until March. After three more even lower-rated episodes, Fox punted the show altogether.
20 of 34 Karen Neal/ABC
Man Up! (ABC)
Also known as: The "manly" ABC show not starring Tim Allen. (By the way, Allen's show, Last Man Standing was renewed.) After routinely shedding a chunk of Last Man's audience, ABC pulled the comedy from the schedule after eight episodes.
21 of 34 Rory Flynn/ABC/Getty Images
Ashley Judd kicking butt? Sounds like a winner. Unfortunately, the one-note premise (if she were to ever find her son, then what would the show do?) had trouble finding and keeping an engaged audience. It was ABC's second lowest-rated show of the season, and by the end of its 10-episode run, almost half of the viewers who watched the premiere had checked out.
22 of 34 Fox
Napoleon Dynamite (Fox)
Even though this animated continuation of the 2004 cult film of the same name reunited the entire cast, lightning didn't seem to strike twice. The showed debuted to a healthy 9 million viewers, but less than half that many were still watching at the end of the show's six-episode run. Gosh!

NYC 22 (CBS)
CBS always seems to struggle with its midseason replacements. (Miami Medical and Chaos, anyone?) This cop drama, from Robert De Niro, about NYPD rookies kept the trend alive, averaging a 1.3 demo rating and 7.7 million viewers in CSI: Miami's old timeslot. The show's final episodes will be burned off this summer.

One Tree Hill (CW)
We thought this show would never die. Alas, its time finally came, but not before the CW rewarded the show's longtime fans with a ninth and final 13-episode season to wrap up the story. And they even brought back original cast member Chad Michael Murray!

Pan Am (ABC)
Bolstered by a strong pilot and decent reviews, this high-flying period drama starring Christina Ricci took off with 11 million viewers. But things got bumpy fast. As the show seemed to spin its wheels creatively, a chunk of the audience checked out, with its lowest-rated episode pulling in less than 3 million viewers. ABC grounded the show for good in February.
26 of 34 Matt Dinerstein/NBC
The Playboy Club (NBC)
Mad Men for network TV this wasn't. The 1960s set drama, starring Eddie Cibrian as a Chicago attorney with ties to the mob and an eye on the Bunny(Amber Heard) who just killed the mob boss, earned lukewarm reviews and an opening-night audience of only 5 million viewers. When that number slid over the following two weeks, NBC quickly shelved the series. Guess sex doesn't always sell.
27 of 34 Adam Taylor/NBC
Prime Suspect (NBC)
Our hats were off to Maria Bello, who gave a terrific performance in this new take on the gritty British crime drama. Despite poor ratings, NBC tried everything to make this one work, often airing repeats to boost viewer awareness. But the effort didn't pay off: The show ended after its initial 13-episode order ran out in January.
28 of 34 Danny Feld/The CW
Sarah Michelle Gellar playing two roles? What could go wrong? Unfortunately, the former Buffy star couldn't save the show from its complicated serialized story line, which made it difficult for the show to find new viewers as it went along. And we're sure the cheesy green screen work in the pilot didn't help.

The River (ABC)
Tense, mysterious and set in a tropical locale, we thought this one might play to the Lost crowd. (It was certainly as spooky as the Smoke Monster.) But this show, which was conceived as an eight-episode series, never really caught fire. After averaging only 4.7 million viewers for its first season, ABC decided to send this one on down the river.
30 of 34 Sonja Flemming/CBS
Despite less than lukewarm reviews, this Rob Schneider comedy actually performed better than any other show CBS has put in the post-Big Bang Theory slot. Still it lagged well behind CBS' other high-rated comedies. No upside down exclamation marks for that.
31 of 34 Marcel Williams/The CW
The Secret Circle (CW)
Apparently, witches aren't as popular as vampires. Although the Vampire Diaries lead-in helped boost its ratings, this one didn't quite become the buzzy pop culture touchstone that its bloodsucking predecessor did.

Terra Nova (Fox)
This expensive and ambitious dino-drama starring Jason O'Mara and Stephen Lang was actually a consistent performer for Fox in the fall. But it wasn't quite the runaway hit it needed to be to justify the price tag.
33 of 34 Giovanni Rufino/CBS
This cop drama starring Without a Trace favorite Poppy Montgomery as a detective who remembers everything she sees seemed tailor made for CBS. But the show routinely lost the audience provided by the network's best lead-in: the one-two punch of NCIS and NCIS: Los Angeles. If you can't succeed with that kind of boost, forget about it.

Work It (ABC)
The most critically reviled new show this season, this cross-dressing comedy needed to be a ratings juggernaut in order to succeed. It wasn't, and ABC pulled it off the air after only two episodes.
