i was looking for something with a bit of grit and I found it in this movie.The acting was very good and the plot was interesting and suspenseful.The characters and the darkness of the movie all contributed to the feel of the movie which left me invested in the characters and how the investigation would play out and affect the lives of those involved. The acting by Paul Bettany and Stephen Graham was intense and the relationship between the two brothers was well developed. I liked the fact it had an ending which completed the story as there is nothing worse than watching a movie and they don't deliver the whole spectrum of the story. Definitely worth the watch.
