Something felt really missing with this movie -- i.e. the action that made the games great.
Despite the high production values, the action (when it actually happened), the story (wasn't as bad as expected, surprisingly), and the visuals being very well done, the movie lacked the action in the first hour that we know and love from the games. There was a great balance with the game from action sequences to the story-telling in-between -- and the movie could've been a good movies, if it had followed the game's blueprint.
Unfortunately, that's the flick's really only fault -- it took too long to get the action going. The action scenes, they just weren't there enough.
