Saw it today. Without spoiling anything, I can't comment a lot....I thought if felt draggy in many places. They definitely could've/should've lost much of the Ron/Lavender/teen stuff and added in some more important things. A few slight changes bugged me.... Overall, I liked it. LOVED Snape, as usual, but it was nice to see him with more to do. Hated what they did to the Burrow. The BIG scenes were well done but still...changed. grrrr....Yes, nit-picking, but I can't help it! Loved Harry on Felix! Fenrir was suitably creepy...I look forward to.....well, you know which scene in DH with him!
Young Voldemort was wonderful! Hero Fiennes is a wonderful actor....he was quite chilling. I agree with whomever said the first teenage Voldy was the better of the 2 but I'm sure he looks too old now.
I have high hopes that they'll make the 2 DH movies with the majority of the book onscreen as it was written.
