I went to see it yesterday afternoon and although I enjoyed it I can't say I loved it. It was my favourite of all the books but I just felt there was something missing in the film.
I thought the special effects were great and the performances of the more well known actors were brilliant and as much as it pains me to say, Emma Watson was the better 'teen' performance overall with Bonnie Wright being some what lacking throughout.
One thing that seriously wound me up was the fact that the kiss between Harry/Cho in the 5th film lasted longer than the measly peck between Harry and Ginny this time around. They took a great scene in the book and turned it to crap. Also, Harry never saw the Room of Requirement so how on earth is he supposed to know where to find the diadum in Deathly Hallows?!
Aragog's 'funeral' seemed a bit abrupt, one of my friends who doesn't read the books found it all confusing and didn't understand what was going on.
Dumblesdore's death was rather moving at the end, I admit I cried. Michael Gambon did a great job with the lead up to it, especially when he was drinking the potion in the cave but I have to agree that it all seemed a bit rushed.
Also, they could have done a better job with explaining the Horcrux's and their significance. Again, friends who only watch the films are more than a little confused.
But it was just a movie, you can't expect them to get everything in which I suppose is always the problem when you have limited time. It's a shame though because now I'm not really looking forward to watching Deathly Hallows when it's released.
