What really made the movie for me was the talent of the actors. I cried, I laughed, and I am pretty sure there were a few times where I couldn't breathe from the tension. While quite a bit of detail was lost in the movie, how can you really expect a three hour movie to capture what takes Rowling hundreds of pages to explain? This said, Yates did a great job capturing the spirit of the book, and he had me on my seat from the first scene all the way through the end of the movie.
I attended a preview screening tonight and was completely blown away by the movie. Once again, I believe that the series is only getting better with each progressive movie.
