Very very predictable, including the post credit scene !!!

Go in cold, and you're likely to emerge with your blood boiling. This has to be seen to be believed.

This is a dark and sometimes deeply uncomfortable drama

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.
