i just want to add to this for a hot second on people the common critique people make on the "katanas are weak as hell irl and are unrealistically sharp and wieldy in fiction" point as a genuine downside.
I'm gonna toot an old horn here but as always, realism isn't a direct allusion to quality. consistency, on the other hand, is. katanas may be unrealistically sharp in fiction but if they remain consistently sharp throughout the duration of said fiction, it can be used to the story's strength. it's maintaining a through-line throughout your story and giving a concrete pillar for the story to sit on. if you start off your story with some One Piece Zoro onigiri type sharpness in your katanas but suddenly veer off into realism territory in order to gain authenticity points, you're doing nothing but shooting yourself in the foot. it'll just become this glaring inconsistency where the katana is useful in one plot point and vice versa the next. now you've proven a part of your story's element to be untrustworthy, and that'll affect the rest of your story's potential suspense, since you've essentially told the audience you're not above changing your in-universe mechanics willy-nilly for arbitrary reasons.
you want to have realism or absurd fun or somewhere in between? whichever works, so long as you stick to it. fast and furious, as a franchise, is an example to this. as standalone movies, they are able to hold themselves but as a franchise?
after seeing dominic toretto level a parking storey with a stomp of his foot and manage to drive out of it alive after WHILE aiding in blowing up a helicopter (that happened in 6, I think), it's hard to take the semi-truck flip crash from the first movie seriously anymore.
