In my opinion, HP6 continues the upward trend in overall enjoyment of the film series.
The only complaint I have is with the sheer amount of stuff that must be cut out of the story to fit it into a 2:30 time slot. I would rather sit through a 3 hour long movie like Watchmen and see the story fleshed out.
Several people we went with have not read the books and were somewhat confused with the leaps that took place between certain scenes.
Overall, I got what I expected. And while I was disappointed by some of the unnecessary changes towards the latter half of the movie, they did a pretty good job keeping with the main themes of the book.
