Why let logic get in the way of a movie's ending? Why do we need script writers at all? Let's just put some good looking people on the screen, add some scary character actors and then blow stuff up. This movie starts outs ok but it is always desperate to find ways to keep this group of backstabbers together. The logic gets thinner and thinner as the movie goes along. It doesn't have a lot of logic to begin with but the ending is so laughably insane that you'll find it hard to believe. Any other special guest villians hinding in the wings? The movie is so intent on "tricking" you that it loses all believability. Just fast forward to Charlize's topless scene and then cut your losses.
