Though the plot line is somewhat formulaic (e.g. Bourne), I was hooked! The story moved along quickly, and the characters were believable (no Michael Bay crap here). The "who dunnit" in the story line required your attention almost more than watching Gina Carano throughout the movie. ;) Knowing she was an MMA fighter, and seeing some of her trademark moves definitely added an element of realism to fight scenes. The ending was primer for a sequel I'd watch a sequel at the drop of a hat, or anything else for that matter!
