I knew what was going to be taken out before I saw the film, but I didn't realize how much this would change the 7th films. In the book, it is very clear that Dumbledore leaves the mission to Harry and his friends specifically and exclusively. This is hugely important in the 7th story, as the 3 really are completely isolated. I think the scenes with Snape were great, and I liked the way they handled the Astronomy Tower. Not sure I've ever seen quite so many innuendos in a PG rated movie, but it was hysterical. Overall, the film lacked a great climax and watched like space-filler. You should see the movie because it is part of the larger whole, but if you're expecting a great stand alone film, don't hold your breath.
