Joss Whedon has become something of a tortured artist since 'Buffy the Vampire Slayer' ended its highly successful seven-season run in 2003. Since Sunnydale was destroyed and 'Angel' got pulled right when it was finding its own identity post-'Buffy,' Whedon has yet to find another long-running hit. It's still hard to believe that a show as great as 'Firefly' only lasted one season!

Whedon's bad luck continues with the recent announcement that Fox is pulling the plug on 'Dollhouse,' a series that had enough of a following -- and potential -- to warrant another season. Would 'Dollhouse' have really hit its stride further down the road? We'll never know. Here are some other sci-fi television series that met their makers too soon.
