This is a passable action thriller. As many review have indicated, it is pretty much a Attack on Precinct 13 storyline. Once it gets going, the action is pretty consistent. Why only 5 stars? One unnecessary character was tasked with blurting out non-funny comedic one liners. Very few films can mix gun action and comedy successful, while maintaining the required tension(DieHard and Lethal Weapon did it best). This movie did not. So too many scenes where you are trying to slightly be concerned with someone's safety, dumb one-liner is inserted for no reason at all(think JarJar Blinks). Outside of that, it could have been a decent action movie.
