I've read all the books and seen all the movies with my daughter and I believe that this one is by far the worst one yet. I had thought that the Half-Blood Prince was the worst but this one has taken over.
I thought it jumped around way too much. Things we mentioned that you would never know about unless you read the books.
But, I think that the worst part of it all for me was that I felt the acting was the worst. Everything seemed to be forced. It didn't seem to come as easy as it had with the first three. It seemed to me that they were just doing this to get it over with. And not just the three main actors but also some of the other supporting characters.
I would NOT recommend it. However, that's just my opinion. My daughter thought it was great - and that's her opinion. So I guess what it comes down to is your own take on the movie.
