I went to see it on sunday and I thought it was good. I've loved all the Harry Potter films so far.
But I do get quite stroppy that it doesn't follow the books - especially all the things listed by PeanutBean. I was lecturing DF on all the changes on the way home hehe
The one thing I really did love in this film was the Quidditch scenes - they were so boring in the first 2 films but in this one they were much faster and fun looking. And I love Ginny and Luna - my faves!!
