Loved it. Hated it. Loved it, hated it, lovedithateditlovedithatedit...
OK, as you can tell, I'm a little conflicted. ;)
Lots of amazing moments--the Harry/Ginny kiss (not to mention the LONG-awaited Ron/Hermione connection), Neville slaying Nagini, Dobby's funeral (sob!), the return of Percy, Molly vs. Bellatrix, and of course the Snape denouement.
On the other hand...the last few chapters seemed rushed to me. I would much rather have had another scene in the immediate aftermath, instead of the abrupt shift to 19 years later. And Ginny really got the shaft--for someone who has been described by the author as a "powerful witch", she didn't get much to do. I suppose I should just be grateful JKR didn't kill her off! ;)
And speaking of killing people off...Fred completely broke my heart (I really want to know how George coped and whether W.W.W. continued), but at least Fred's death had some weight to it. Lupin and Tonks seemed sort of gratuitously tacked on the end, like "Oh, and incidentally...". From a literary perpective, it was deeply unsatisfying...no details on how/when/who. I think Lupin deserved better.
But I'm not obsessing. Really. :P
