Hmm. Time to rant.
Half-Blood Prince. This book frustrates me to the hair-ripping point because:
1. LENGTH. Jo- we LIKE to read what you write! It was too rushed!
2. HARRY AND HERMIONE. Yes, I'm a shipper, but she just blatantly seemed to rip them apart- I think she got tired of people guessing "Harry or Ron" and just comepletely destroyed their relationship. I don't know about everyone else, but the eye-rolling-scathing-Lavander-gut-hating-typical-horrible-NOT Hermione was not present in the first five books.
3. KING'S CROSS. It's a little thing, but it bugged me that she just cut it off at Dumbledore's funeral.
4. HARRY. Does anyone know what he was thinking? Besides having totally-random-out-of-no-where-I-love-her Ginny daydreams? Can we say, "huh?"
