Top 10 Sci-fi Movies
In an interesting upset, Sci-fi mag "SFX" in Britain had a vote on the top 10 sci-fi films of all time.
1. Serenity (2005)
2. Star Wars (1977)
3. Blade Runner (1982)
4. Planet of the Apes (1968)
5. The Matrix (1999)
6. Alien (1979)
7. Forbidden Planet (1956)
8. 2001: A Space Odyssey (1968)
9. The Terminator (1984)
10. Back to the Future (1985)
On its own, Serenity doesn't rate that high (imvho), but as a payoff to the series, it is powerful.
It's about the only sci-fi series that comes close to the golden standard - the original Trek series - in terms of story-telling, action, and humor.
You can get the whole shebang - Firefly, the series, and Serenity, the movie which ends the series - for about $35, plus whatever shipping, and for as many hours of great entertainment you get, it might be one of the best tickets out there.
