I did, and I loved it!!!
I read once that JK Rowling gave an interview where she stated that she reviews the scripts before production to ensure that they do not cut anything out of the movie that is important to the series as a whole. That being said, I was SHOCKED that Dumbledor's howler to Petunia was not in the movie! I always assumed that the fact that Dumbledor and Petunia had been in contact was going to be important.
Also, although I'm sure it isn't important to the series, I was sad that Hermione and Ron being made prefects wasn't part of the movie, because my favorite part of the book is Dumbledor's line at the end when he explains to Harry why he wasn't selected for prefect.
I loved the interpretation of Azkaban, and I thought the actress that played Dolores Umbridge did an excellent job.
Anyone else see it?
