Honestly I don't see why the reviews are so bad. The acting as well as the cinematography, the story and the tention built, where very good. It's a common story with very surprising plots wich makes it really original. It kept me entertaint and tense from the beginning till the end. Also the way the movie was filmed was very beautiful and artistic. This could definatly be an arthouse spy movie. As I said I thought this was one of the greater movies I've ever seen. I think you could compare it to shutter island.
