I have kind of a love/hate relationship with Harry Potter Universe. I read the first two books as a kid when they've been released and then stopped because I start reading Pratchett's Discworld and discovered the different between a perfectly written book and a poorly written one, the difference between a cheap world building and a massive and inclusive world building with strong characters. I, actually, in my youth get bored pretty easily with HP universe by JKR but was kind of interested in the fanfictions (not all of them) i start reading and found way more developped and inclusive than jkr work. And then few years later i discovered that JKR was a poor excuse of human being and it cool off any little interest I had in HP. 

I don't recommend buying or consumming product from HP universe as it now served only to give more platform to a bad writer and a really bad person. Trans people Matter. Inclusivity matter.
