Great movie, very faithful to the book. I suggest re-reading Deathly Hallows before seeing the movie, but as long as you've read the books the movie will make sense. As all the professional reviews have said, if you are new to HP this is not the time to jump in. Also, if you are one of those people who has just seen the movies and hasn't read any of the books, go read the books first. Several of the previous movies have left out plot details essential to the final chapters of HP, and you will end up confused and complaining that you don't get the movie.
