I knocked this one out pretty quickly because i was sick for four days and didn't feel like doing much else. Unfortunately i didn't think it was nearly as much fun as the Goblet of Fire, but that's not to say that i didn't enjoy it. 
 Harry was kind of an idiot in this book. He's fifteen, he's got a lot to be angry about, but it was painful watching him screw up over and over again and ultimately get someone killed. Dumbledore took the blame for what happened, but it was kind of like he was saying "i should've realized how stupid you were going to be." Harry's jealous, he treats Dumbledore and Cho like crap, he risks people's lives just to chat with Sirius when he could easily just use the damn mirror he was given to talk to him, he refuses to do what the Order instructs him to do--as though Dubledore has ever been anything but brilliantly benevolent--and he loathes Snape despite all sorts of insistence and even proof that he should not. He's just a big silly mess and it makes sense that he falls right into Voldemort's trap. 
 The plot of this one wasn't as interesting as the last one. And Umbridge is in it messing everything up, so that's frustrating. At least there was a bit of vindication at the end, although i thought the whole end battle was sort of muddy. All the kids walk away from it for some reason, but Sirius easily dies? The things i liked about this book, namely Luna and the D.A., were not in it nearly enough. It would've been great to have Harry and Ron kick some butt together at quidditch, but that didn't even get to happen. At least the Weasley twins got to have some good fun torturing Umbridge before they dropped out of school.
