Netflix has a great recommendations system based on what movies you've rated in the past. I have a bit of an addiction to rating movies - it's really easy to find and rate movies you've seen, and the recommendations are usually dead on.
Anyway, thanks to Netflix, here's a list of my five-star movies. Feel free to comment if there are some that you agree with, some you don't agree with, or movies you think are deserving of the list.
Being John Malkovich
Eddie Izzard: Dress to Kill
Ferris Bueller's Day Off
Mitch All Together
Robin Williams: Live on Broadway
Shaun of the Dead
The Truman Show
