I honestly don't know why there is so much bashing for this movie online. Maybe a "Few Peace Loving" people took offense and brought it's rating down. But it is one of those extremely well crafted movie with amazing performance. It also displays how well a cinematographer can choose angles and tell the story in a claustrophobic environment. Even though I felt the runtime could've been lessened by 10 mins or so, it isn't a big deal at all. I loved the movie and would suggest it for everyone reading this to watch. You will not regret it.
