The first Transformers was so amazing you'd think they'd at least try to make the second one decent. The only reason I gave it a 3 is for the good action sequences and Megan Fox (not for her acting). On the other hand, there were simply too many cheesy lines, the love story wasn't believable, and many of the scenes relied on Shia to pull off scenes that were corney and quite frankly lame. And how does Rainn Wilson get a top billing in this movie? He was in the movie for maybe 10 minutes. He added NOTHING to the movie and yet he gets a "Starring" billing? Still, you have to see this one in the theatres if you loved the first one. Doing so will at least curb your curiosity and will allow you to form your own opinion.
There's no dobut that this is an excellent film. It was a bit too long and could have been cut by at least 10-20 minutes. There's way too much hype, too. Regardless, you'll enjoy the movie very much. Go see it!
