my personal top ten:
Aliens - The ultimate mix of sci-fi, action, and horror.
The Blues Brothers - Madcap comedy with great music.
Die Hard - Pure action.
Halloween - One of the most original - not to mention genuinely creepy - horror movies ever made.
Pulp Fiction - A strange and unique drama with many twists.
Raiders of the Lost Ark - A rip-roaring adventure in the tradition of the old TV serials.
Star Wars trilogy - Groundbreaking sci-fi entertainment, truly epic in scope.
Terminator 2: Judgement Day - Sci-fi action doesn't get any better than this.
Unforgiven - Rather unique Western that spends most of its time deconstructing the genre.
The Usual Suspects - The ultimate whodunit, a superior action/crime drama.
