MASH was a movie first, that seemed to work out. Star Trek did well with their movie franchise. I liked the X-Files movie, but it was really just a long episode. If they make another one I will be happy. Stargate SG-1 seems to have garnered a good fan base, and is more popular than the original film. I think there is a sort of zero-sum thing going on, where if a TV show is very popular a movie will flop, and vice versa. (Dukes of Hazard, X-Files, MASH, Stargate all fit the mold) Star Trek was always popular, but I don't think reached the level of smash hit or flop in any incarnation (other than the new spinoffs which won't become movies), so it still fits the mold. I'm also happy that Firefly is being adapted into a movie. A very good TV show that never made it but got a cult following. I just don't think there is a single answer to that question.
