Wow
It was epic. Simply and utterly epic. There were amazing performances all around, especially from Alan Rickman, (Severus Snape) who got his shining moment in this film. There were also some absolutely stunning special effects, which got better with each slain horcrux.
Some things were altered from the book, but overall, as much as it pains me to say, I think the movie ended things much more clearly than the book did.
In closing, I advise everyone to go see it! This is a movie to satisfy all parties: the die-hard fans, the new fans, and even the casual movie-goer. I was excited for this movie's release, and I was not disappointed.
