Firstly, I don't think I'd ever call it a perfect film. It did have some key flaws that did ultimately affect the character development and I'm not sure how I feel about the parts that were excluded (I won't go into detail for those who haven't seen it).
I enjoyed the movie quite a bit. It followed the book well and I like the changes like Hedwig's protection of Harry and Dobby's extra appearance. I think the acting was pretty good and the special effects were amazing (as usual).
I believe there will be points where moviegoers may be a little put off with the choices, but overall I was pleased and would definitely say see it for yourself!
