The story is neither bad nor good it's mediocre. so we have the main premise "turn Nezuko back into human" the story revolves around Tanjiro a 15 yr old boy and Nezuko, his little sister. In Ep 1 we see his family get slaughtered by demons and his sister turned into one. This is the main driving force for Tanjiro and what started the whole series. After that, we meet his mentor Urokodaki and one of the shittiest "training arc" in shonen history, the training arc only lasted 2 eps so you can already see the problem in it. The training arc was so rushed and done so quickly that it doesn't feel 2 yrs passed by. After this arc, KNY gets filled with a lot of tropes that further add mediocrity to the show. The Powers or Breathing techniques are awesome but it's not meta. The story is ok but it's not great. Storywise I will give KNY a 5/10.
The Art of the show has to be its strongest aspects. KNY is animated by Ufotable, the studio that animated fate/zero, fate/unlimited blade works, and fate/heavens feel. The fight scene was good enough to entertain me but it didn't entertain me as much as other shonen shows did. The choreography is ok, the effects are really nice to look at, and overall its a nice looking show.
The sound is also great, it properly conveyed moods and matches the whole show. The OP and ED are ok, Gurenge by Lisa is definitely a banger.
Now here's one of the weakest aspects of KNY, the characters. the characters are Flanderized to the point which it annoys me. We have Inosuke a tsundere, and Zenitsu a horny ass loud asf character. The show tried to add comedy by adding Zenitsu into the mix of characters but throughout the whole series, I didn't notice my self laugh. The other characters are good but I didn't get emotionally attached to them. The only thing that I appreciated was Nezuko cuz she's cute asf.
Overall KNY is a show that excels in the art department but it definitely doesn't deserve the hype it gets. It's a mediocre battle shonen anime that doesn't have originality and filled with tropes. If you're going to watch it don't expect stellar writing cuz it's only a good looking show.
