As a fan of the Transformers cartoons, I was worried when I heard Michael Bay was directing the film. I did have some hope though since Spielberg was somewhat involved though. Too bad the movie was molded more from the creative liberties of Michael Bay's ego than it's source material.
Some things that made this movie suck: Bumblebee playing cupid despite having more pressing things to worry about like Decipticons, Starscream's lack of any personality especially since he was one of the most entertaining personalities on the show, Optimus Prime tip toe'ing around a garden like a worried soccer mom, Barricade just kinda dissapears, Sector 7 was stupid, the government drama was horrible, the transformers seemed like more of an afterthought since they only came out a few times.
If you liked the movie, great. Enjoy it. But I found it butchered by Michael Bay.
