Mostly of the same genre. Tthere are other great movies, like "The Green Mile" or "Apocalypse Now", but I usually won't watch a movie more than once if it's too heavy - I don't want to watch a movie that makes me feed bad <g>
Lord of the Rings
Star Wars
Forbidden Planet
The Matrix
Groundhog Day
Blade Runner
(almost every Pixar movie)
12 Monkeys
