I started reading Kimetsu no Yaiba since the anime was getting tremendous praise, but it was kind of a waste of time...

To be short but sweet, the premise of Kimetsu no Yaiba is incredibly interesting with demons and demon slayers being allies and foes alike. Most of the characters are compelling and unique not only in their design but also their abilities. However, the manga is terribly paced. It feels like the growth of the characters and the story are inconsistent and relatively, like a bumpy road. The art is not that amazing nor special in my opinion (at least for the manga). The only reason why I read Kimetsu no Yaiba was for the hype and at the end of it, I felt like I was reading KnY simply for the interesting concepts (rather than characters or plot).
