I decided to take a quick look through 2010 and am running through seeing very few and then realized...I was working 90-100 hour weeks that year (and 2011 and 2012). I'm going to need some recommendations, too.
I second or third or fourth the recommendations of Winter's Bone, Restrepo, Exit Through the Gift Shop, Tiny Furniture, and I add Animal Kingdom (fantastic smart thriller), Get Low (but I'm a sucker for Robert Duvall), Another Year (but i'm also a sucker for Mike Leigh), Never Let Me Go (rare successful film adaptation of a book), 127 Hours (I guess not exactly a "small" movie), and Blue Valentine (rawr).
