Funny that reading this thread suddenly reveals how poorly science fiction has done on screen. Only one or two of the films mentioned are remotely good as films that an adult could take seriously -- "Minority Report" (until near the end), "Blade Runner". That is about it. Not much for an entire genre. I can only think of a couple more -- "Aliens" and "2001". There must be one or two others that are good films, period, but one is hard pressed. Terminator II is an excellent film. One does sort of run out.
