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.

"We tell the stories others refuse to tell." - Richard "Ringo" Langly

Like many of you, I have a growning collection of DVD sets from shows that left the airwaves too soon. If I had to pick just one to have back, it would probably be Firefly, but The Lone Gunmen would certainly be in the conversation. It was a great example of a spin-off done right. After years of service, fighting the good fight, lending a hand to Mulder, the boys finally got their own gig. Melvin Frohike, Richard Langly, and Johy Byers weren't your typical prime-time, leading man, characters, and The Lone Gunmen wasn't your typical prime-time show.

(S05E11) When I heard that we were going to be doing an X-Files week for Retro Squad the first thing that came to mind was "Killswitch." It has long been my favorite episode of the series. Aside from being a great story, it also serves as a marker for where my interest in the series changed.

By the time they made it to "Killswitch," X-Files had started to lose me with the mythology episodes. In the beginning it was almost annoying when there would be a standalone episode. I was so engrossed in the bigger picture story that it was like being forced to take a week off from that which I was really interested in. By season five, though, that interest had waned. Not that the show had gotten bad, just that it was pretty clear that those big answers weren't coming any time soon, so I started looking forward to these episodes more and more. And for me, "Killswitch" is the pinnacle of The X-Files in that form.
