Tokyo Ghoul is amazing in my opinion. The mood the art style sets, the interactions between characters, and the overall plot are outstanding.
Kaneki is a sweet and caring character. Even though later on he somewhat looses this aspect of his character, he still maintains his baseline humanity. The story really is portrayed well. If you watched the anime first and are deciding whether or not reading it would be a waste of time, I can assure you it's not. The anime sucked. The manga is amazing. I like seeing all the character development and epic battle scenes and especially the times when a protagonist goes insane for a bit.
I honestly have no words but outstanding.
Chef kiss.
