Fred. And Dobby. Lupin. But really, mostly Fred, even though Dobby's funeral had me crying something terrible. He (Fred) had the best freaking line in the book though, regarding Voldy. "...he can run faster than Severus Snape confronted by shampoo when he wants to." I nearly died. Thank God she kept Dumbledore dead. Thank you, thank you, thank you. I can deal with Harry living and Snape actually being good (both of which I thought would happen anyway, so it wasn't really that big of a disappointment), so long as Dumbledore stays in the grave where she put him in Book 6. Holly, you were so right about the Harry/Horcrux thing...but not his eyes. *grins* And she made Neville a hero!! AND when he got the sword out of the hat he got the confirmation that he belongs in Gryffindor just as much as Harry does. What else? Oh. Ron. When he took off early on, I never doubted he would be back. It was only a matter of when.
Right now I am having problems thinking of the things that I wasn't so fond of, but off the top of my head the Snape/Lily thing was a tad annoying...although it is interesting to note that when Petunia mentioned "That boy" and Harry thought she meant his father, he couldn't have been farther from the truth. And then there was the Harry naming his second kid Albus Severus (such a mouthful, but nowhere near as bad as Scorpius...I wonder if JKR watches Farscape?), but I could actually buy Harry doing that...apologizing to Snape for not believing in him and saying he appreciates his sacrifice the only way that he could, seeing as he's dead and all, so I don't know if it bugs me or not. Gimme time.
But all in all, I have to say that I liked it. I mean, sure, she killed off some of my fav. characters, she made Snape good and she kept Harry alive. But she also made me actually like Harry again, which to be honest I didn't think was going to be possible.
ETA: also, Molly kicking Bellatrix's ass? Was lovely. :D
