Despite posting the Independent Spirit Award nominations and the National Board of Review's awards, I think I'm going to stray from reproducing all of the critics' awards and best of's for 2008, as you can easily find them on IndieWire, GreenCine or MovieCityNews if you so desire. Instead, I'll post a link here and there to the sites.
The Washington DC Critics Association named Slumdog Millionaire the best film of 2008. Kyle Smith and Lou Lumenick of the NY Post concur.
Gomorrah swept the European Film Awards, winning Best Picture, Director, Actor, Screenwriter and Cinematographer. Roger Ebert lists 20 of the best (narrative) films of 2008, and five docs, in no particular order.
Sight & Sound in the UK has posted their 50-critic poll of the best films of 2008, per UK release date (sort of). With three UK films on the list, the top 10 is as follows:
1. Hunger - dir. Steve McQueen
2. There Will Be Blood - dir. Paul Thomas Anderson
3. WALL·E - dir. Andrew Stanton
4. Gomorrah - dir. Matteo Garrone
5. (tie) A Christmas Tale [Un conte de Noël] - dir. Arnaud Desplechin
