I'm gonna say yes only b/c the fans were able to save Chuck but couldn't save Firefly. I think Firefly fans may be more diehard but smaller in numbers.
If they were smart, they'd re-air the episodes and plaster Whedon's name all over it as the director of Avengers...
I dunno. I think it will surprise you. (Not speaking for myself... I have no intention of sleeping on the ground for anyone.)
Don't get me wrong, I'm a huge Chuck fan and I went to the panel last year, so I'm not trying to argue which is a better show or anything, but I believe Firefly will be a bigger deal than you think.
I'm not sure that comparison is super valid. Chuck was on the fence after 24 episodes that were aired in a prime timeslot, Firefly was cancelled after 11 episodes that were aired out of order on a Friday night. In 10 years it's fan base has grown a lot due to the movie and the constant re-airing. At any rate, we can talk about it elsewhere, if you'd like. I don't want to take up any more space in this thread. (sorry mods!)
