Films That Just Get Better With Age ...

For me:

Blade Runner
The Matrix
The dollars trilogy
Battle Royale (still seems fresh to me, even after HG)
Hard Boiled (I don't think will ever be topped as an action movie)
Videodrome (prophetic in parts)
The Iron Giant
Back To The Future (will always be cool for me)
The Goonies (still popular with kids now)
Pulp Fiction (a cultural milestone)
Scream (still popular with teens today)
Something by Martin Scorsese

I know that I'm missing quite a few, but that's what I can think of now...
