Same can't be said about story or characters.
Talking about characters:
1) Tanjirou - the main hero - the ultimate case of "Mary Sue". Increadibly perfect and boring character: brave, strong, good. Speaks in generic style, easily triggers by any kind of evil (his mind turnes off). Has no real weaknesses (outside from "being too good")
He trains for about two years (almost nothing from his training gots actually shown) and from zero becomes powerfull swordsman. He bravely charges into every battle while knowing nothing about his enemies, magically survives and then always pulls some sort of power trick to win the fight.
2) Zenitsu - secondary hero - wimpy character to the point of absurd. He is constantly afraid of everything, constantly cries about something. Also, he is INCREADIBLY LOUD, shouting different kind of nonsence. Those his traits show up all the time, making Zenitsu increadibly hard character to endure - at least for me.
He made his moves twice in entire show - and both times he was fighting, while being asleep. Fainted out of fear and then fighted... I can't even add those actions to his account. It's like his body fought, not actually Zenitsu. Sadly, body is not a character
On an upside: Zenitsu is kind and has weaknesses to overcome. Too bad those weaknesses owerwhelm him entirely
3) Inosuke - secondary hero - stupid character. Considered to be strong, yet loses to Tanjirou in the direct and simple fight. Generally, does almost nothing usefull in the entire show. Inosuke killed one demon when made his appearance - that's all. Oh, and once he used his technique too find an enemy in the forest. Now that's all.
Inosuke was like worse version of Tanjirou - he always charged into battles because of fighting lust, but actually didn't won in any.
On an upside: Inosuke was somewhat funny (bacause of his blunt attitude). Brought fun to this otherwise boring show. Yet, even in "Jester" role he seems mediocre.
4) Nezuko - can't say too much about her, for the most part of the show she was either sleeping either... standing silently, i guess. Nezuko has almost no personality. All i can say - she was kind and remained kind in this weird state of hers. She supports Tanjirou, yet shows almost no emotion to other characters. Cute. But boring.
Talking about story:
It is linear and predictable. Also, scenario repeats itself one episode after another: strong demon appears - Tanjirou charges - demon dies. Most of the quests heroes received from talking crows - crow say "do this and this" - hero does. Why they trust those crows so easily? How heroes recieve payment? Why everybody has to pass such stupid test in order to become a demon slayer? (i mean, most of contestants die, it is just ridiculous). Too many questions were left without an answer
The main villain of the show has interesting design, but only on the outside. On the inside - it is generic cruel villain, who tortures his minions for failures. He had a good opportunity to kill the main hero himself - yet he gived this task to his pawns
All in all, There were way too many holes in logic, story, worldbuilding... Characters were annoying. I couldn't fully enjoy the show, most of the things felt stupid and unreal
Art and music are great, but they don't justify poor writing.
I am greatly surprised this show gathers such big scores. Ratings and friend's reccomendation were the reasons for me to watch Demon slayer. I became dissapointed as a result
Similar shows I actually enjoyed: My hero academia, Assasination classroom. Those are far from being perfect too, yet they had nice characters and more convincing world settings
