Saw the Harry Potter finale over the weekend. It was pretty good. As a series I think these movies have done the best job overall of translating large story lines from books to the screen. My overall take on the movie series is quite good. I will enjoy owning them as a set whenever they come out. They seem like winter movies to me, though - maybe because most of the action throughout takes place during the colder months of the school year.
Specifically regarding this movie, there were, again some changes from the book. For the most part they were unnecessary, but not burdensome. Were I a crazy purist like I am with the Lord of the Rings I would probably have disliked them, but such as they were, they were OK. The special effects were appropriate and didn't overwhelm the story, and the characters were well-performed again. If you liked the other Potter movies, you'll like this one.
How 'bout them Huskers!
