I can't see major plot holes either, but then I wasn't really looking - I was all WHEE I LOVE THIS STORY. Plus I'm not really a canon freak, anyway - I mean, JKR sucks at continuity, so I'm back to the "are you new?" reaction. But I wub a couple of people who hate it, so oh well. I won't diss their reasoning, I'll just snuggle it to my (fabulous, actually) bosom.
