I watched this movie because I am somewhat of a fan of Michael Fassbender, and the previews seemed similar to other movies I like. However, I wish I would have read the reviews, particularly those listed here, because they are EXACTLY like this movie: long and boring and never got to the point!
I will just say this: this movie is slow and the end is anticlimactic. I respect other's reviews and opinions, but clearly they're not regular movie buffs, they must be pure cinemaphiles. If you're looking for action or something like "Collateral", keep looking and save your 2 hours for something else.
