First of all the CG sucked. Second, Michelle Rodriguez can't act. She rolls her eyes to the back of her head with every line as if to make it more intense and stronger, it doesn't work. The movie doesn't really follow the game much. And although I never thought about this until I heard someone else say it, why would the computer send out all those little lasers and not just the "net laser" if it's job was to kill any and everything? The answer is, so they can include more unecessary action without incorporating it more smoothly and intelligently.
