I loved that movie. Not so much because of acting quality but the fact that I was fan of Transformers since I was a kid and seeing them on big screen made me feel good.
It was a job well done considering the fact that they had to put sci-fi robot cartoon into todays world. Not an easy task, even more so since lots of people loved that cartoon and wouldn't appreciate a half baked job on it (Uwe Bowl comes to mind here).
