Everyone has hit most of the good ones, so I'll list some of mine that aren't as good, but still solid.
The Mexico Trilogy El Mariachi, Desperado, Once Upon A Time In Mexico
The first two Predators.
I like a lot of the View AskewniverseClerks, Mallrats, Chasing Amy (not so great), Dogma, Jay and Silent Bob Strike Back (eh.), Clerks II (it had it's good parts.) stuff.
I did like the animated series they made out of Clerks, but it's not a movie so.
I wish I could say the Matrix, but I just can't.
Ghostbusters
Gremlins
Terminator (The new ones are now a guilty pleasure.)
There's probably more.
