This is definitely a movie for the people who have read the Harry Potter series.
This movie was much better than the most recent Harry Potter movies. I believe that many of the previous Harry Potter movies suffered from trying to cram too much into a single movie. This movie does not have that problem. It is true to the book. I didn't have the disappointed feeling about scenes that didn't make it that I had when watcing previous Harry Potter films.
This movie captured the feel I remembered from the book very well. While there are funny moments, the sense of the dark times never lifts. The complicated relationship between Harry, Ron and Hermione was captured perfectly.
This may be my favorite Harry Potter movie to date, and I can't wait for part II!
