I think Transformers pwns 2007 cinema. Despite the fact that the year isn't even over. And that isn't just because the rest of movies this year are weak. In fact there are not bad ones like Pirates of the Carribean 3 and Ocean's Thirteen and possibly The Golden Compass, but Transformers is simply in a class of it's own.
The Simpsons Movie looks to be excellent stuff as well, a potential challenger for Best Film of 2007, but I think it'll lose out by a slight margin to this OWNAGE movie about Autobots and Decepticons.
As I said, Transformers are pure ownage. It's that simple.
As for the rest, Shrek 3, Die Hard 4, Hairy Pothead and the Order of the Penis, Fucktastic Four: Rise of the Silver Surfer, etc, they can all go shit themselves.
