Although the book differs from what the movie offers, the movie goes for a more entertaining approach such as in its romance-humor between Ron and Hermione, Harry and Ginny, and others. It's true that some scenes are depicted differently from the scenes in the book and I was a little frustrated by the ending, where Harry was not stupefied under a cloak. Otherwise, it was still a great movie and I'd recommend it to anyone who can deal with the differences between book and movie.
