Revenge of the Fallen certainly delivers in the action department. The fight scenes are mind-blowing.
I was able to follow the plot, but it did seem to jump around a little bit.
The Transformers altogether get more screen time, but many of the characters are just kind of glanced over.
My one major complaint is the crudeness of the movie. Some moments are funny, but there are so many crude references and so much profanity, particularly for a movie based on children's toys. It all just felt so out of place and took away from my overall enjoyment of the movie. I absolutely would NOT take a child to see this movie.
So overall, mostly enjoyable, but needs changes for next time.
