@nickos114 ... Don't add up? From what I saw, the only flaws in the movie are technical (which can be a little distracting to the initiated, but, not enough to detract from the experience). As far as the story is concerned, it's an underdog survival thriller: pretty straight-forward. Get from point A to point B without dying.
Just awesome!! Not one thing I would change about this flick. Great acting by all... Kate Beckinsale and Hugh Jackman being superb per usual in any of their films. A movie you can watch and watch and not get bored. Definitely recommend!!! Cheers! :)
