I genuinely did not find anything interesting about Tanjiro as the protagonist. The side characters range from hilarious (Inosuke) to legitimately interesting (Nezuko) to downright annoying (Zenitsu). Those are the only saving graces for the characters as I don't remember any others, even the villains. Some have interesting design choices and I give credit for that but damn are they dull.
The animation and art style is the obvious highlight of the show. Its downright breathtaking. Its a shame a really cookie cutter show with a cast of mostly bland characters holds it back from its full potential.
