The movie matched the book very well, having the same dark tone. It matched the text much more closely than the last few movies, but like all movies based on books, there were some changes (makes me glad they decided to split the long book, rather than cut much out). The action was great as well. My only complaint is that the movie ended on a sad note, which made me leave the theater more sad than excited. As usual, the movie had some funny, and some happy parts, but much of it reflects the desperation that the world is in now that Voldemort's power is growing.
