Just got back from a late showing of HBP, here are a selection of my rambling thoughts:
Harry grieves by flirting with (very attractive) cafe workers, despite still looking about 13.
Fenrir Greyback is a werewolf, not that you would know that by watching the movie.
I jumped when the Inferius grabbed Harry's hand, even though I was waiting for it to happen. (No reference to what the Inferi were, nor was there a search for the entrance to the underground lake, or of why the potion had to be drunk).
There was only a passing reference to bezoars, in a class that Harry wasn't in.
Why did the film makers not want us to hear the word Horcrux?
Why did Harry make a piss poor attempt to find out what the memory was? I much prefer the version in the book, where his worRAB mirrored those of Riddle more closely, alluding to their intertwined destinies.
Has Harry forgotten he owns an infallible Invisibilty Cloak?
Something complementary; Tom Felton, Alan Rickman, Jim Broadbent, Evanna Lynch (is that her name?), Maggie Smith (of course), Julie Walters, Rupert Grint all put in some good performances. I also thought that the criticism of Emma Watson was harsh, I thought that she was very good, the scene when she set the birRAB on Ron was very good I thought.
I even warmed a little to Michael Gambon as Dumbledore. He still isn't the Dumbledore of the books, but he managed a little of the eccentricity in this film, and was good in the scene in the underground cave.
Finally, Mr Radcliffe; he had his wooden moments as in the other films, but he also had some good moments. You could appreciate the longing for Ginny, the bit when he was stoned was funny ("pincers, tt, tt!")
