While there was lots of action & special effects, there was litte plot. I fidgeted in my seat for the first hour wishing it was over; then the action picked up and caught my interest. The director could have cut half of the movie without losing anything. Too much unnecessary crude humor. In all fairness, I've never read the comics, so I may not have an appreciation for the characters. I liked the first Transformer movie better. My 20-something sons and their friends loved it, tho.
