I saw it last night, and I enjoyed it. Simple as that.
It's meant to be a movie where you just sit back and enjoy the essence of the books come to life (read: ESCAPISM). If you are a hard out fan of the books you will probably not enjoy the movies as you will be analysing it too much. If thats you, Tough luck there sunshine.
I enjoyed LOTR emmensely -and accepted that it was an adaption to fit a film format. Had it been 100% true to the books it would have sucked (losing Tom Bombadil & the Scouraging of the Shire was essential, some changes were so-so, but I accept it's someone elses vision of how to adapt it best, and opinions can differ). I cant say the same for the HP books to film adaptation as I havent (yet) read the books, but probably it wouldnt have translated well either. Probably the best way to enjoy HP is to not read the books until after you have seen the films. Or to switch off the analytical part of your brain and simply enjoy some movie magic.
