When it comes down to it, comedy is often about character, which is why some of the best sitcoms of all time are just about people being their kooky selves. Kramer's unique way of opening doors on "Seinfeld," Chandler's distinct speech patterns in "Friends" and Carla Tortelli's sick burns in "Cheers" all drew audiences into some of the greatest sitcom universes on television.
Other shows haven't been so successful.
PrettyFamous, an entertainment data site by Graphiq, ranked the worst sitcoms of all time. To build this list, the data experts looked at all sitcoms with over 1,000 IMDb votes and ranked them by Smart Rating -- a weighted score out of 100 that takes into account a show's IMDb votes, IMDb rating and the number of Emmy awards won. Ties between shows were broken by the number of IMDb votes.
There are many reasons why these shows missed the mark. Some are spin-offs that failed to capture the magic of their predecessors. Others may have relied too much on convention or celebrity and not enough on creating really compelling characters. In the case of ABC's "Cavemen," the producers literally tried to make a 30 minute sitcom based on a character from a Geico commercial.
From flops like "That '80s Show" to unsuccessful adaptations like "Clueless," check out this list of shows you probably won't see on Nick at Nite any time in the future.
