I just got back from this. It was very pretty to look at, but very convoluted and hard to follow plot wise. At least in this one there wasn't as much racial stereotyping, however, so that's a plus.

My biggest beef with the movie is pretty much what everyone else's is that I've ever seen; there's too much emphasis on the human characters, and not enough emphasis on the transformers. They're like secondary characters in their own movie. Even so, they like introduce new autobots in like every movie, so the team is never the same. Not that they ever get much development anyway. But anyhow, every seen with Sam Witwicky trying to get a job, work at said job, and impress girlfriend, really detracted from the actual plot of the movie that anyone cared about. I would get into it every time I saw what the decepticons were doing, and then get right out of it again when Shia came back on screen.

There were a lot of things I didn't understand.
SPOILER!!:
Where did those decepticons on the moon come from? How did the autobots get captured before the scene where they're going to be executed? How did the humans get out of the building that was leaning impossibly?
Most importantly though, why do humans seem to think they're on the same playing field as the transformers on any level? Why do we have two movies in a row were some stupid FBI person is trying to order the autobots around? Why even bother to try direct combat with a transformer when your ordinary weapons seem to generally have negligible effect on them? We've seen in past movies humans trying to fight transformers, and just getting their asses kicked. They're still trying at points in this movie, although at least they get smart about it and try sneak attacks and such.

I will admit there was some cool stuff: the transformers themselves. Shockwave was pretty bad ass, Laser Beak was pretty scary and bad ass, Sentinel Prime was epic with the voice of Leonard Nimoy, Megatron had a pretty bad ass look, and Optimus, of course, kicked ass (when we saw him.) There were some good actors in this: John Malkovich, Ken Jeong, Alan Tudyk, and of course John Turturro. They were all supposed to be comic relief in some way, shape or form, though the only one who really made me chuckle at all really was Tudyk. The girl was better than Megan Fox-she didn't seem like a bitch outright, although she was still kinda just there as the "requisite" love interest.

Overall, it was better than Revenge of the Fallen, but it might've been the installment that I enjoyed the least, simply because I've had enough of Bay's bs. If there's another one, I don't know if I'll go to it. Pretty much the only reason I went was because I heard it was getting positive reviews. Interesting. I think I might give it a 3 out of 5, although that might be stretching it. Anyhoo...
