I was forced to read Harry Potter and the Philosopher's Stone for grade school and fell in love with the series ever since.
Favorite characters are probably Ron, Luna, Sirius and Hagrid. Least favorite is probably Hermione, or at least Hermione in the last books. She got on my nerves a lot.
I wish the series would pull a Star Wars and have a bunch of different media at once, with comics, television and novels by writers other than J.K. Rowling. The Fantastic Beast films just don't do it for me and Crimes of Grindlewald felt weirdly corporate and clinical, not the imaginative and whimsically dark adventure the last stories told.
No but seriously, I want Harry Potter comics. Now.
