Memento, with Kill Bill a close second.
Just about any movie with the Govenator in it, but especially Predator and Commando. Kick some ass, Ahnold!
Falling Down is a pretty good one.
I don't know, I kinda felt like his reflections and actions through out the movie were acts of vengeance upon society. Maybe I just liked that he fucked a bunch of shit up.

Mine is Titus starring Anthony Hopkins and Jessica Lange. Add it to your netflix que! It's truly evil modern adaptation of Titus Andronicus.
