I'm very sad about the Harry Potter series, and i loved reading it the first time around (that was shortly before the last 2 movies came out).
On the one hand, I loved reading the books - I devoured them in record time and lost quite a few hours of sleep because i just couldn't drop them after starting with Order of the Phoenix.
On the other hand, I learned afterwards what a foul human being JKR is. I'm someone who can split the art from the artist, and normally i would just do that as long as JKR doesn't see a penny from me, not even as PR (i borrowed the books, but i was in the cinema for the last 2 movies - can't undo that).
But the reevaluation of the books after JKR's twitter tirades made some themes obvious for me that are not that visible if you don't look for them - or don't want to. The treatment of the elves, the nearly all-white-school, the only black teacher called Shacklebolt, the using of jewish stereotypes for goblins... I am pretty angry at JKR for souring something I enjoyed, and I was pretty angry at myself for not noticing many things earlier simply because i let my guard down.
Looks like i fall into the first group, even tho i was around 30 when i read the books. Only defense i have is that i am not a native speaker and read them in english.
