Not necessarily my top favorites, but I'll add them anyway:
Tron. For it's day, simply magical use of visual technology
Same goes for Star Wars.
Meet the feebles (more for the experience...)
All of Trey Parkers movies I've seen, and yes this includes Orgazmo.
Pitch Black was fun
And recently, V for Vendetta. Very brave movie really, to make you question what a 'terrorist' is, if you didn't already. Even with it's odd pacing and random lesbians.
My brain is dead, can't think of more
