The movie keeps true to the original story, with the exception of a few minor changes that don't effect the overall storyline. Tom Felton does an excellent job as Draco, and at times you want to feel really sorry for him. Helena Bonham Carter is incredible as Bellatrix Lestrange, and you can't help but feel mesmerizing by her presence on-screen. The scene at the cave with Dumbledore and Harry is the best in the entire movie. It shows you how big of a role they play in each other's lives. This all leads to a climactic ending, and you can feel the emotions of all the characters on-screen. The ending was really well done, and makes me look forward to seeing what they do with Deathly Hallows.
