It all went downhill to me at about the fourth book.
I don't think so. I think these books are actually better because they're less childish and more dark, although I'm starting to get tired of Harry being pissed off all the time and even biting the heads off of his closest friends. Although I guess they could justify it by saying he's absorbing the rage from Voldie and becoming more like him, but Voldie never loses his temper, he's very cool and collected and calm. And I still think they don't act enough like teenagers.
I have a great respect for Dumbledore now. Taking on a bunch of wizards and kicking all their asses at once? I mean, Shacklebolt (ha ha!) might have helped him, but I think he just stood there and did nothing.
I have an even greater respect for Hagrid. I can just envision IDE being like a well-toned Hagrid, busting out of his cottage, spells bouncing off his chest like they're nothing, and him tossing wizards 50 feet away with a swipe of his hand. For Hagrid to kick the crap out of all those wizards and take off running, that's just wicked.
And poor Snape. Harry needs to sit down and talk with that guy, let him know he feel sorry for him and he's not like his father. But Harry's too prepetually angry at everyone and sorry for his self to actually care about other's feelings.
