I literally just got home half an hour ago from watching it! It is really, really good. Possibly the best one. Much more action, the story line is good, a couple parts were confusing for my boy though. It is more violent than the first 2. I'm a huge Transformers fan, went to the midnight showing of the other 2. Love the first ine, tolerate the second and loved this one. @Cheryl, you won't be confused at all since you didn't see the second one.
Yes it is long (2 1/2 hours) but my 7 year old sat through it fine. Warning, the first time they show the new Megan Fox, it is a butt shot of her in panties. The new girl is not bad either. Other than that, just Michael Bay's normal hot girl shots lol.
I read a review on yahoo, and the guy said it was the best one, and he warned of the butt shot. Critics hate action movies anyway, I never listen :) I'm not planning going to the movies again til Captain America! Cars 2 can wait til DVD lol. If you go, let me know how you liked it
