This Movie is an Amazing movie and i recommend it for everyone. However it has had 3 movies in front of it who have made almost all of the design choices for it. the film future for the potter line is fairly well set in stone. The looks of the sets and costumes will not change in the future which stops this moving from fulfilling its artistic potential, but that is problematic of all book-movie conversations. What is left to be artistic is the directorial view (i.e. camera motions, filters, lighting levels, staging etc.) this film (as well as Prisoner of Azkaban) is darker than the rest, which sets it apart and gives it it's "unqiue factor," that is the element that sets it apart from other films of the same type. most interesting to me is the study one can do in plot line. if you have not yet read the books and you are a artistic individual i would recommend you not read any more books till you have seen the movies of them. to many people this is an unconceivable thought but please listen to my logic. first off i have read the first 3 books and am reading the 4th now. every time you see one of these films there is always going to be someone there who read the book first and these individuals all sing the same chorus of "they cut so much out!!" this is true. However if you ask those who have only seen the movies they will say they understand the harry potter plot line. that is because while Rawlings books are very entertaining and have many many side stories and interesting facts about her wizard world, her book s are still largely "fluff." and that is why i made my recommendation. you can see these movies make coherent plot lines out of these books and not included every detail. looking in-depth at these changes after you have seen the movie makes both the book and the movie better in my opinion. this study in plot analysis will give you a more keen mind to what makes a story and what doesn't. i encourage everyone to try this, if you still can, and your movie going/book reading experiences will become much more enjoyable.
For those who are curious, i suggest seeing the movies first then reading because obviously the books offer more information and when seeing the movie it can become more difficult to keep the two separate in your mind. if you start with the smaller and add to it things will stay more organized and you will be able to flush out Rawlings style, making the books more enjoyable. thanks you.
