I did love it and I think the characters were developed perfectly, however, I was a tad disappointed with a couple of sections

Spoiler (Hi light to read)

The whole "Harry is a horcrux" was just too predictable. I remember arguing in the Flourish and Blotts threads that Jo wouldn't go down that route as it was too easy. So I was a bit disappointed (and ego a bit bruised) when I read that section.

I also would have like to have read more about what happened afterwards. The epilogue was just a bit too short for me. I wanted to know what came of certain people in the series and how the ministry changed afterwards. Maybe that will come in the encyclopedia.

It would have been cool if the teachers had been developed a bit more. You really only got to hear about Snape and Dumbledore, it would have been nice to know a bit more about McGonagall and Sprout and a few others.

I'm currently re-reading the series so I may be back with other things I've picked up and would tweak.
