Most anime is either a guilty pleasure or a guilty displeasure for me. The stuff I like, I feel embarrassed of the part of me that likes it, and I feel embarrassed about what I'm willing to overlook to enjoy it. Then the stuff I don't like, I feel closed-minded about it, like what's wrong with me that I'm too stuffy to enjoy it or too dumb to get it. But I don't have friends or acquaintances who are into it, so it never comes up with other people, and I generally don't think about it.
Oh I understand this one too much as a fan of the Isekai genre. So much slop and poorly done power fantasies. But some amazing content in there. Then I look at something like One Piece and not really vibing with it at all despite being overwhelmingly popular.
