If you pay attention to such things, the New York Times has an excellent section on its website dedicated to the best films of 2008. Two of the slide shows - one on the aging of Brad Pitt for The Curious Case of Benjamin Button, and one on the recreation of a 1970's political campaign for Milk - are particularly fascinating.
The Golden Globes air next Sunday night. You can see the complete listing of nominated films here. I've only seen two on the list - The Dark Knight and Kung Fu Panda.
