I've seen it twice and it's a very powerful film. More people need to see this movie. The acting and cinematography (sp?) were both wonderful.
It has been a very long time since I got lost in a movie because I usually look at them on the technical side, but I got very drawn into this movie. It felt as I was in the moment as they were. Also the extremely long takes (longest is just over 6 minutes) makes it more documentary style and at times it didn't feel like a movie but more like watching history. Very moving, go see it.
