If people want an exploration of sci-fi ideas don't look for it in a Star Trek movie or in just about any mainstream sci-fi movie but instead pick up a novel by Alastair Reynolds, Iain Banks or Asimov and other writers. And maybe some Star Trek novels as well. It's easier to explore these ideas in print. Film is too much of a visual medium to do it effectively (though I'm sure some of you can come up with movies that do). Star Trek especially TOS was about telling cool action adventure (and the occasional comedy) storylines with some superficial ideas thrown in to the mix to give it some substance.
