Excellent adaptation.

I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

It's complicated... I really like the directing, acting and writing but, there are issues with the way it's shot that I just can't deny. As much as I love the storytelling and the fantastic performance but, there are also certain scenes that didn't need to exist.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
