If you know Michael Bay, ask him to employ an editor next time. Basically it’s 2.5 hours and about 0.5 hours are wasted time, it’s full of stuff that just doesn’t contribute to the film. I really do hope that they get a new director for the next film. It will do well, undoubtedly, but it’s going to be the momentum of the first film carrying it through, not this one.
Personally I would wait for it to come out on DVD, since I can’t really give it more than 6/10. I was actually waiting for it to finish, which is never a good sign. I think it was an indication of possible boredom. Considering I gave Terminator 4, 6/10, I may well have to put Transformers down to 5/10.
