I'm not a big fan of the films that were considered the top that year but there were plenty of good and great films that year.

Oldboy, Rize, 40 Year old virgin, No Directin Home, Enron: the smartest men in the room, The squid and the whale, Last Days, Hotel Rowanda, Hustle and Flow, A history of violence, The Constant Gardener, Good Night and Good luck, Grizzly Man, Downfall, Cache, Millions, Broken Flowers, Kung Fu Hustle, Kiss Kiss Bang Bang, Mysterious Skin, Devil's rejects, Sin City, and although not everyone would agree but Jarhead, Crash and The Woodsman.

There's rarely terrible years for films, it just you have to seek out the good ones and can't depend on hollywood's trough to feed it to you.
