If you are looking for Citizen Kane, don't watch this movie. This film is about providing mindless robot violence entertainment. And boy, does it deliver that in spades.
Great fight scenes with the robots and the best FX and digital animation on screen since Pirates III. There is one story line: stop the fallen at any cost. That is plenty for me, I just want to see some action!
Great action movie. Not as visually stunning as Star Trek, but plenty of fun.
