Not going to repeat anybody else, but there are some great ones on here. But the list is sadly missing:
Robocop
Wild Zero
Crank 2: High Voltage
36 Chamber Of Shaolin (aka Shaolin Master Killer)
Battle Royale
Big Trouble In Little China
A Boy And His Dog (aka, I kid you not, Psycho Boy And his Killer Dog)
Snatch
Six String Samurai
But seriously. Someday I'll post my reasons why Robocop is one of my favorite films of all time. I'm a huge movie person, I love really well crafted films that are meaningful and deep and insightful. Robocop has all of that and is stone cold bad ass.
