Natural Born Killers is a fantastic kind of over the top and straight face burlesque piece by Oliver Stone. The story is by Quentin Tarantino and makes fun of the tendency of some people in the early 90s to glorify violence. It's done a sort of kaleidoscopic fashion with extremely solid yet completely farcical characters. It's gripping, it's violent, it's intelligent, it's powerful.
A must for everyone, unless you don't want to see violence or blood.
