My favorite / most crushing, exhaustive film experience at Sundance this year. Here's what I thought: http://mikeluciano.blogspot.com/2010/01/sundance-2010-recap.html

One of those films that's hard to explain how it gets to you. I found it almost scary at times. If you give yourself to it and can take the extreme gradual pacing, it lulls you into meditative trance where every action and expression is amplified. Awesome film, see it twice.
