For the record, I wasn't very happy with where the movie took the story; not just the killin' off main characters (and everyone they ever knew in the TV series, oh yes the man did) part, but appearing to drop the "Blue Sun" connections in favor of a simplistic "Eeeeeeevilll Gummint" background. Well, fine; governments are all evil, despite the best of 'em being less evil than anything else our species has tried. For story-telling purposes, complicated evil is way more interesting than simple evil.
That said, it's still the best movin'-pictures SF ever, especially the television series. Kirk's a mewling kitten compared to Mal. (And just for fun I might add he could whup R-- P---, too, except I don't want to start the debate).
