A mind twisting ending to a shape shifting story line creates a fantastic, mysterious, emotional thriller.

Rating: 10/10 (27 September 2012)

This movie is hands down, one of the best I've ever seen. I just finished watching it and even though I'm 5 years late I just had to write a review about this.
The plot of this movie could so easily bu turned into a dull, simple, boring action movie, however, the selection of characters, the great soundtrack and the great acting makes this a masterpiece.
I found myself supporting every character at some point of the movie only to get my head turned around into disagreeing with them as the movie progressed.
Casey Affleck steals this movie with his touching performance. At times a loose cannon, at others, a compassionate catholic, contemplating right and wrong. Ed Harris as always provides some of the best peak action moments as Morgan Freeman maintains his dark, quiet role behind the shadows.
The movie really manifests the nature of Boston. The people, the accents, the old bars, the drugs, you actually feel as if you're strolling down the blocks, investigating every lead that comes to your mind. The actors were very authentic and everything seemed so natural, as if you were actually watching what's happening as a bystander.
This is far more than just a story about a kidnapping, it is a struggle between the forces of darkness and light, a fight between right and wrong, and the ending will haunt for a while after you finish watching it, thinking about what you would have done to handle the situation.
Must not be missed, as said, one of the best movies I've seen to date with an absolutely intense, mysterious and thrilling plot that keeps you on the edge of your seat for the entire time.
Easiest 10 I've ever given to a movie.
