Caught it this afternoon. It was like the Fast and the Furious meets the "Ocean's" movies. Crazy. The ending left so much room for sequels and spin-offs as to be almost ridiculous. Some serious, over-the-top fun. Enjoy it for the summer popcorn flick that it is.
P.S. - Somebody should have given The Rock a handkerchief for all of that sweat. He looked miserably hot in that heat for the entire movie.
