This followup Transformers flick has everything the first movie had, and more of it. That isn't always good. The movie is about 45 minutes too long, has a VERY lengthy battle sequence near the end that takes up way too much time and is confusing and tiresome. There was more adult content, more bad language, Sam's mother was more crazy, etc...but it didn't make for a more enjoyable film. I especially found the "shooting" to be hard to watch - cameras too close to the robots, and too much movement to see what they were doing half the time. It was just a blur of metal.
But, if you liked the first film a LOT, you will probably be satisfied.
