Yeah i agree totally, There are a lot of issues and mistakes made in Transformers 2 which is a real shame since the first was so well done. It was like this was rushed out just to get some more cash or something. The Transformers were way less cool, and the bad ones were not even a problem, it was like it was a completely different series that the first film.
Also i had a problem with the sound, the movie's lack of a good soundtrack really hurt the film a lot. it needed a good soundtrack to accompany all the action scenes, without them most were kinda boring. Also the sound effect quality in general was not up to par either.
I think I'm gonna go with 7/10.
