I really liked it, except for the bits with the humans. I thought they were silly. I don't think secret government conspiracies work like that, and I think Optimus Prime should have just reached in to the house and taken the glasses if they are that important anyway. There should have been more bits with just the Autobots or Decepticons talking, and not so much stuff with just military people talking, unless the whole movie is going to be US Army vs Transformers, which would be cool but they didn't really do that. I don't know what the hacker bit was about, unless it was supposed to be like Chip in the cartoon series, who shows up for absolutely no reason at all.
Off bad, onto good: Optimus Prime and Megatron and Ironhide and Starscream and Blackout and even Bumblebee were cool! Frenzy was also cool, even if he was a cross between the robot from Short Circuit and a Gremlin. I just wish they had had Ravage and Soundwave in the movie too.
Oh, and please God do not let them kill Optimus Prime in the next movie, because that happened in the cartoon and it was really sad.
