So many awesome movies in this list. I'm not sure I could pick just one... Harley Davidson and the Marlboro Man was just... beautiful. So was Army of Darkness.
One that hasn't been mentioned yet that is one of my personal favorites is Sin City. Also, Boondock Saints, Pulp Fiction. Not high drama, but entertaining as heck.
KgB- Would I have to see the first 8 to be able to understand what's happening, or does it stand on its own reasonably well?
