I got to a late night showing of Transformers tonight, and just as a word of advice, pick another day. Southlake Town Center was packed with people going to see the fireworks.
The movie was great! It was long enough to make a good story without feeling rushed. The robots were great, and as sci-fi goes a lot more believable, than in the cartoons.
Definitely the blockbuster of the summer, and well worth the price of admission.
