Ok bear with me:
The definition of overrated is something that doesn't live up to its reputation or the hype surrounding it. An example of something that would be described as overrated is a restaurant that everyone says is delicious but which really is just OK.
For what the show is and for the people that only watch the anime, for me I cant see it as *THAT GREAT of an show that does better than all other series* but you dont need complex stories to break number or something very new in the Demoghraph and I'm fine with that (but shitty isekai garbage), then again it's also for the casual viewers.
And atleast I dont hate an series for the sake of hating that is already a world record breaking series to get clout. I can call it overrated cuz people swing the word only as (a little buit famous show than "X" show) or only got hype once and never talked again or for the sake to trigger people.
But if I get these fans why they like the show, only for episode 19 while other animes also exist with similar dramatic meaning ... yeh,, it's hard to talk with these people.
All in all it impacted the causual viewers cuz believe it or not, you will always have millions people that are new into anime that have no knowledge about a demograph/genre/ or anything, this doesnt only apply for anime.
How kimetsu impacted was the dark aesthetic taisei era (were normally the edo era is the one that people resonate for watching japanese culture/anime for the old days), so that made it unique on it's own core. Besides that...
it's all about simplistic phasing/setting/goal/characters, with something like kimetsu made it perfectly mold with it's unique artstyle.. with tanjirou being an very kind mc with a passionate oni-chan persona and forgiving, people often say that it "break" the mc cliches when you have something similar already like yo (shaman king) or ichigo (bleach).
What I'm trying to say is, its overrated for what it is for being nothing actually new or refined with people calling it #1 anime of the decade with these many numbers broken records.
break so many records they fast cuz of the *ANIME* & episode 19 of our lord ufotable & why it onl works on kimetsu than other show is cuz of its simplistic concept that grab millions of casual viewers easily/ the mc & the aesthetic that people dont care about talking.
I'm really happy for the author imo, it's hard to make it into the business succeeding that much
I freaking love kimetsu, I read it since ch 14 came out and the aesthetic alone is what I was invested. Since I'm into art myself, The way the author use the breathing style for oldschool art of ukyio is wonderfulll
But if you say to me to be quiet for an series that is 22+ years established for being a phenomenal icon of an series that people hardly can replicate into their own story.. than you are asking to get hated on with actual arguments, I do agree on couple points with u with One piece. No series is perfect, that is something you have to know, it may look for u that people act that way but so do the fandom for kimetsu and literally every show.
Some are debatable for breaking doors/ being revolutionary or refined the Demoghraph.
I dont find kimetsu THAT good of series that makes kimetsu better than one piece.
Thanks for reading
