I think that the comment section is specifically to lay out your thoughts and interact with people, doesn't matter if their take is different from yours
Also there is some truth to what he's saying...up until chapters before 90-80 almost everything was unique, chaos and randomness but at some points the usual shonen tropes, unnecessary out of nowhere drama and characters acting outside of their ...well character started to kick in...
hence the in-the-middle backstory
the "oh no she/he's dead" but saved by something, rendering the death scene mute and literally a bait and switch
the characters that have been fleshed out since the earlier chapters start acting in the weirdest ways almost completely different from what they used to, almost like they're robots reading lines
So yeah, he does have a point.
Articulate yours so we can understand it better, legitimately do it, the more interaction the better
