I stopped reading about halfway though and that was when they were being released. I’d say my mounting issues at the time was the weird pettiness of the good characters, the cheapness of Harry(why didn’t he pay for the car he helped wreak? Why didn’t he pay rent to the Weasley family?), and books ending with cheap drama(how many times did Harry loose a positive father figure?). If you want a larger breakdown, here’s a good one that goes into a lot of detail.
