Good question...where has all the good Sci-Fi gone on TV.
At the box office, other than the next Star Trek movie coming up and the Star Wars franchise trying to capitalize on 3-D, the space-based genre doesn't offer much. The super-hero genre seems to be popular, but has a lot of re-makes. With a re-vamping of Batman, Superman and now Spider-man, Hollywood seems to be running out of ideas. The X-Men series has possibilities, but I'm not sure if they have anything in the works. Going by the following list and links, Sci-Fi needs some new life.
5 X-Men movies
6 Star Wars movies, 1 Animated Star Wars movie
5 Superman movies, 1 Supergirl movie.
3 Spider-man movies, 1 on the way
4 Terminator movies
4 Alien movies, 2 Alien vs. Predator movies
4 Predator movies, 2 Alien vs. Predator movies
6 Batman movies, 1 on the way
11 Star Trek movies, 1 on the way
3 The Matrix movies
3 Transformer movies
The following site lists the upcoming movies as Sci-Fi, fantasy and horror. If you subtract the fantasy and horror films, The Sci-Fi list is small.
