I remember feeling like they kinda botched Dumbledore's end scene. Otherwise, it's fine. I was never a huge fan of that book though, you really feel the "middle-chapterness" of it as its just setting up all this stuff for the finale.
As for Deathly Hallows Pt. 1, I'm genuinely surprised that people seem to love that one. I have to wonder if it's just the fact that it stays super faithful to the book, because to me, it does not really work if you're not bringing your knowledge of the books in with you. Dobby's death scene in particular feels woefully unearned, as he's had like 15 minutes of screen-time 5 movies ago, and then another 10 in this one, and suddenly we're supposed to feel like this is some huge moment. If you pretend the books don't exist, I don't think it works as a fulfilling narrative (unlike other "part 1" adaptations like Fellowship of the Rings for example).
Part 2 may deviate in ways fans hate, but it's at least enjoyable as a magic-themed extended action movie. But I admit to being odd man out on this one. I was never a fan of how that book handled the final duel (with Harry winning on basically a technicality), and I much prefer just having a full on magic battle between the two of them. That movie does lose major points for not showing how several major side characters bite it, I don't know what the hell they were thinking there.
