If you don't want to be confronted with discussion of a bad manga in the comments to a bad manga, then might just not read the comments at all, or you might block the commenters who point to the ways in which the bad manga is bad. Otherwise,
you're voluntarily continuing to read what you believe or pretend to believe to be bad, and then complaining that anyone would continue to read something that he or she thinks is bad. 😁
(The business of reading bad comic books and manga, of watching bad movies, of reading bad novels, of viewing bad painting, &c,
knowing in advance that they are or will almost surely be bad, has been discussed many times and sometimes at great length.)
