Harry Potter and the Deathly Hallows: Part I (2010)
Directed by: David Yates
Screenplay by: Steve Kloves (based on the novel by J.K. Rowling)
Starring: Daniel Radcliffe, Emma Watson, Rupert Grint, Ralph Fiennes, Bill Nighy, Helena Bonham Carter, Jason Isaacs, Tom Felton, Brendan Gleeson, Alan Rickman, David Thewlis, Rhys Ifans, and practically every other British actor that's ever lived.
Overall, Deathly Hallows stays very true to the book, which automatically makes it the best film adaptation so far, in my opinion (but it's still not my personal favorite HP movie -- that one is and will remain Prisoner of Azkaban). The kids -- er, actually, they're all adults now, but you know what I mean -- have grown tremendously as actors since the first movie. Daniel Radcliffe has been pretty spectacular for a while now, and it's obvious from interviews that he really works hard to develop his craft. Rupert Grint has really come into his own over the past few films, and he is particularly good in Deathly Hallows. Emma Watson has always been the weak link for me, but I was quite impressed by her performance this time around...she has several emotional scenes that she executed perfectly.
Things that would have made the movie better:
1. The scene from the book where Harry and the Dursleys say goodbye. WHY is that scene not in the movie?! Dudley needs his redeeming moment, damn it!
2. More Severus Snape. Oh, hi Alan Rickman, you were only in one scene? Huh. That's strange considering you're a pivotal character. But I guess most of his scenes will be in Part II. Now that I think about it, the first half of the book is pretty light on Snape as well.
3. The full Bellatrix/Hermione torture scene. I completely understand that they had to cut it to keep the movie at a PG-13 rating, but it still would've been awesome to see.
4. A little more explanation about Regulus Black and the locket horcrux. "Oh, R.A.B. is Sirius' brother and he stole the horcrux from Voldemort" is not enough.
I must also mention a scene that wasn't in the book that I felt was a perfect addition to the movie. Normally I am very anti-additional scenes, but I simply adored the scene where Harry cajoles Hermione into dancing with him to a song on the radio in order to cheer her up after Ron leaves. It was just so sweet, and it was an excellent way of showing the brother/sister relationship that Harry and Hermione share.
