So what did I think?
What I really wanted out of this book, I got: Snape was vindicated. Fewer people died than I thought were going to, though I always said one of the twins was going to be killed before the end, and I was right [sniff] Overall, I thought it was a good ending, and I'm very glad she did an epilogue -- Albus Severus! [another sniff]
And that about covers it. I'll leave the blow by blow reaction posts to other people!
Later: Oh, yeah, feel free to leave spoilery comments. And beware that there may be spoilers in the comments, so on and so forth [g]
