This 6th installment of the HP series was very good but a bit disappointing to an avide reader of the books. Lots of important parts were missing from the movie including the battle at Hogwarts when the death eaters gain access inside the castle. It was a bit confusing for the non-readers because they didn't explain how Snape was the HBP. My husband liked the movie but was asking questions throughout the movie and I had to fill in the gaps for him. Overall, I really enjoyed this movie, just a bit disappointed in the exclusion of some key parts.
