On one side you have the fanboys who would lick the sweat from his armpits rating this a ten, and the I hate Vin Diesel crowd (who probably didn't bother to watch the movie) giving one star reviews. Despite it's flaws this is an entertaining, slickly produced, mindless sci-fi/action film. Vin Diesel knows what he's good at and he does it pretty well, if you're expecting something else that's your fault.
