If you want a couple of movies with theatrical merit, check out 2001: A Space Odessy, and Kelly's Heroes.
2001 is just a great Sci-Fi movie that everyone's seen before...same as Kelly's Heroes. The link that bounds them? Simple. They can be viewed in so many ways.
Sure, you caught the space exploration thingy stuff, the dangers of technology, and the influenece of extraterrestrial life the first couple of times but there's alot more going on then that.
And Kelly's Heroes, well, sure it's funny, and there's lessons on greed (plus some pretty damn accurate portrayals of WWII equipment, although I STILL dunno what kind of plane attacked them on the hill and destroyed the half tracks) But again there's alot more going on then that. If Crapgame's story on how Kelly got busted, didn't tip ya off, there's alot of betrayal vs morality stuff going on. It's bluntly put out there, but the comdey kind of draws away from it. There's also considerable anti-war stuff going on too (Odd Ball and the tank crews is the most obvious) dealing with Vietnam.
Seems like everytime I watch those two I find something new. Thats what so bad about The Matrix...you catch nearly everything the first go round.
