The action doubled from the first one. There is way more fighting in the movie watching it in imax and the wonderful sound you recieve makes you feel like your in heaven. Optimus Prime finally gets his justice and Micheal Bay finally lets the audiance see how much of a bada** that he really is. The mechanical action is very much inproved. Some racial stereotypes that could have been left out. So basically if you want a great action movie with an ok plot line. But as a summer blockbuster its gonna have the same critics finding something wrong with it. I give it two big thumbs up.
