This is precisely why I enjoyed the movie.
In a word, it was "fun." It has some big problems with characters randomly and inexplicably appearing from nowhere, a rail gun that stops being used for no apparent reason, waaaaaay too much lame sexual humor only funny to 13 year olds discovering that boys and girls are different, and a rather anti-climatic ending, but it was fun. It is the cartoon come to life and is completely unapologetic about it.
A question on the score, supposedly Jablonski worked in the original Transformers theme and "The Touch" from the movie, but I never heard either. Did anyone catch that at some point?
