Yes I just saw it yesterday. It only came out then. It was awesomely cool! Man, I cried when Cedric died. I didn't in the book, but the movie made it sad.
I thought Dumbledore was a bit cold towards Harry. For instance, after Harry's name has been pulled out of the goblet, Dumbledore slams him up against a wall and demands to know whether he put his name in or not.
In the books he's not like that at all!
It was strange. The characters act differently to how they do in the books, but it still was fabulous!
Krum was really scary in the maze. His eyes! And it made me jump and scream (yes in a packed movie theatre!) when everything is silent and he's walking along when the maze suddenly closes up behind him.
