My favorite movies of the past year:

Be Kind Rewind (Awesome! It's not on video yet though, I saw it in theatres. Jack Black + Mos Def erased all the movies at their rental store and have to remake them for their loyal customers.)
I am Legend (Terrifying!)
Michael Clayton (George Clooney is a 'fixer' turned good guy. "I am Shiva, God of death!")
Perfect Stranger (Hallie Berry investigates the murder of her best friend. So good.)
Children of Men (Mankind has been sterile for the past 20 years, when a young African girl--in the now war torn and immigrant-hating country of Britain--gets pregnant. Clive Owen gets roped into bringing her to safety.)
Notes on a Scandal (I'm not going to ruin the plot for you. But it's twisted and oh so good.)
Daywatch (Russian film. Sequel to the mediocre Nightwatch. Light vs. Dark. Surreal, dreamlike, but with lots of good action. Had several good strong female characters. You don't see that alot in movies today--or is it just american movies?)
Hard Candy (Girl/Psycho vs. Paedophile/Good guy? See it! So intense.)

Oh, and I second Stefan on Hot Fuzz and Planet Terror. I liked Death Proof as well. (Planet Terror and Death Proof were part of the 'Grindhouse' feature put together by Quentin Terrintino and Robert Rodriguez. They were shown together in theatres in the US, but separate everywhere else. Yeah I've misspelled a couple people's names in this post.)
