Basically, anything that wasn't giant transforming robots was terrible, and that was kind of a lot. Because this movie is looooooong and has WAY too many characters. There were so many characters that got, like, one scene and their stories never got resolved.
But it's pointless to complain about the lazy plot development of a Transformers movie. When you sit in a theatre, and the lights dim, and the first two things on the screen are A Michael Bay Film, Produced by Hasbro Toys...you know you are not going to be seeing some quality cinema.
I did find myself getting way more excited than I expected when the Autobots and Deceptacons were doing their roll calls. And just in general every time they talked or moved or transformed, it was very dope. I thought the robots looked great, and they were very big.
But crazy jerky camera work left me wondering what the hell was going on most of the time, particularly in the battle scenes. It was just really hard to watch, sometimes.
It is a good summer time at the movies, though. It ain't summer until Michael Bay blows something up.
There is one specific point I want to make about the movie, but I'll post it in the comment thread.
