All of them before the point that I can legally say Emma Watson is hot.

All of it

The Deathly Hallows was trash. Killing of characters just to stop the idea of continuing the story. Three wizards running around the world hiding just so happen to come across vital information? The elder wand is Harry's because of a punch? He uses an unforgivable because of spit? Snape didn't hate Harry? Bullshit. Dudley didn't hate Harry and everything is ok between them? Double bullshit. I've killed his bitch ass just for saying 'no hard feelings' or whatever the hell he said. The only thing good about it was the story of the Deathly Hallows and the feels during Dobby's death. I [u][i][b]loved[/b][/i][/u] the first 6 books but that last one was awful. It took everything and said "lol, jk". It was sloppy. It was almost offensive to the fans.

Chamber of secrets for me. Hands down, no contest.
