I don't want to list my problems with this part right now, because I really do love it, and ther is so much to love. The material that works, as is usually the case with this series, works SO, SO well. This is certainly the closest a Harry Potter film has been to its book since CoS, and I am never one to think the movie should replicate the book, but there are many scenes that are exciting in part because they are so close to their book counterparts, with dialogue taken straight out and quite well.
Acting-wise, there was no weak link, there rarely is, but I really think Emma did some outstanding work here. I've always loved her (um...as an actress...too), but this is a huge leap forward; Part 1 is basically hers.
