With Oscar written all over this hard-to-watch film, you will have trouble deciding if its the performances or everything else that makes this completely spectacular. Not only does the best actor seem like a lock, but there are some amazing supporting performances as well. While not as insanely violent as Django Unchained, this movie will still make you wish you were somewhere else when watching some of the more difficult scenes. It's powerful in how it can make you feel powerless. Chiwetel Ejiofor has come a long way since Children of Men, it is hard to believe this is the same actor in some ways. He is outstanding.
I believe it will be held in the same regard over time as Schindler's List in how it is very revealing and does not hold back for one second.
Strongly recommended, essential viewing.
