I had read reviews saying this movie was the most loyal to the book out of all the Harry Potter films, but I disagree. While it was indeed a good movie and a good adaptation, certain changes were made that did not make sense, to me anyway. Having read the book numerous times, I was disappointed in the loyalty aspect. The acting, photography and set design were very well done, some of the plot seemed to be a bit choppy. Bit it is still worth seeing.
