I feel like the reason why Baki, one punch man s1, all of dragon ball, Ippo, and megalo box did do well with the action even in comparison to other shone isn’t that the combat is realistic to say but that it’s coherent. Those shows don’t feature overly complicated magic systems or spam special effects anywhere near as much as other anime, so it’s easier for viewers to register what the fuck is happening even if they’ve never watched a single anime series in their lives.
Like fuck, I’d be lying if I said I could understand anything happening in one piece much less fairy tail in any scene compared to the average hand to hand exchange in dragon ball or whatever fights Lee is in in Naruto. All the isekai that get pumped out are even worse when it comes to making fights completely incoherent.
