I read the books this year because I wanted to feel pain, basically, and I wanted to be justified in disliking Harry Potter. I was not disappointed. However, I still don't understand how the fuck the end of the book worked. It was so harebrained and convoluted and sloppy as fuck that I don't know what actually happened. Am I stupid or was it a bad ending? And what the fuck happened? How did they actually kill Voldemort?
Wait so, holy shit, no wonder it didn't make any fucking sense to me. None of it was defined beforehand and it was revealed like all of her other sudden twists that explained everything but actually were held together with glue and spit in other plots of the other books too. The entire series is just fucking M. Night Shyamalan all the way the fuck down.
Alan Moore said that Rowling used ill-defined magical principles but you laid out precisely why he said that. He was written off as a crank for saying it, but he's absolutely correct.
The seventh book very obviously ran into the dilemma of "oh god oh fuck i have so many loose ends and my protagonists are in such deep shit there is no way i can tie this all together". AKA the Kojima/Lost dilemma. Deathly Hallows was an admirable effort but the cracks in foundation are extremely visible
