I agree with all the points you brought up. I saw it a few hours ago. I loved Snape in the study Hall also.
You were right there were many double entendre, especially where Hermione says Krum is more of a Physical being(?)
I loved Myrtle in the bath scene, she wzs way more provocative in this movie then in the books, or the second movie, lolz. I also loved how Fred asked Angelina.
What I don't get is why Voldemort was so tame, I expeted this huge evil darkness thing, but I did love the dark mark tatoo, it looked better than I thought it would.
I still can't beleive they had goyle put his hand down Crabbe's pants, :)
