SPOILERS AHOY!! (I didn't think anyone still lived who didn't know how the Harry Potter series ends, but on Facebook I was proven wrong. So. SPOILERS, YARR!)
1) Maggie Smith rocks. By stepping out between Snape and Harry early in the movie, and dueling Snape straight out of the castle, she once again proves her awesomeness without even saying a word. Is there insurance I can buy to make sure I, too, have the steel and charisma of Dame Maggie when I'm elderly?
2) I find it ridiculously entertaining when actors get to do disguise-potion identities, such as Helena Bonham Carter pretending to be Hermione pretending to be Bellatrix.
3) Young Snape in his Pensieve flashback (which all of a sudden resembled one of the more romantic Tim Burton movies) is pretty much designed to make us Gothy-hearted types fall in love with him. But I do think it annoying and unjust--or just stupid on Snape's part--not to let us, or practically anyone else, see that attractive side of him, like, ever. Okay, so he was a double agent and had to be noxious to the good guys. But I don't know; he seemed to actually hate them. And that irks me.
4) I'm so glad the Hermione/Ron kiss didn't involve a house-elf discussion. However, getting drenched by dead-basilisk-infused water doesn't seem like the tidiest time to mouth someone else's face, either. Oh well.
5) Why am I crying so much at this movie? Why is Rupert Grint making me cry most of all? I was not prepared for his reaction at finding Fred. Sidenote, however: if you didn't know about Fred, and you were watching the film on a computer screen (which I was), you might've had trouble figuring out who they were kneeling and sobbing over. It's a bit subtle. But since I did know, it was very very sad and effective.
6) LOL at That Awkward Moment When Lord Voldemort Hugs You. Jeez, I never felt sorrier for Draco. (But I was proud of him for clearly not wanting to step forward and join the Dark Side.)
7) Neville's speech was another weepy point. But I wanted to step in there with a wet washcloth and interrupt him to take care of his head wound. It's a mom thing, perhaps.
8) Signs I'm getting older: Daniel Radcliffe looked handsome to me all middle-aged up. More so than usual, even. He also resembled youngish Michael Douglas a little that way. Huh. Odd.
And finally, irrelevant to this particular movie but still funny...
