Having read the book there were some noticeable differences that made the translation into the film different. Taking out almost all the mystery behind Dumbledore and the utter hopelessness of the situation. The book did a better job to express the utter lack of all hope the book conveyed in trying to figure out how to find the remaining horcruxes. I can also see why many would not like the film as its formula is so different from every other book/film. Still I thought they did a great job with it and like how you can easily see all the lessons learned from the other films come to fruition in this film. I do wonder what will be done in the second part as most of the book is seen in this film, but I'm just happy there is a film to see. You'd have to be a fan of Harry Potter to enjoy it, but as most of the planet already is I'm sure you'll find it to be an enjoyable film.
