I have come to absolutely hate the obvious self-inserts of authors, when done in a way that looks like a day dream of a teenager with power fantasies in puberty. Or when the whole story caters to an audience that loves to do that as well. All these isekai-level999-cheat-skill-harem mangas that have been popping up in the last years are what I have in mind specifically, but I have also seen this in actual books. Especially books with teenagers as a target audience, they tend to either over power the protagonist, giving him ridiculous plot armor, while also trying to make him look imperfect so that all the "misunderstood" teens in the world can see themselves in them, and so on. I saw this in Harry Potter for instance. The author made it a point to call Harry a regular normal boy all the time, when in fact nothing was ever regular about him. And then he suddenly got rich, was famous, but still tragically misunderstood, magically talented in sports, the favourite of the teachers that matter, and somehow still part of the uncool clique. Riight.

It's all so terribly obvious and totally boring. Every teenager had always had these day dreams where they suddenly are the center of the world, and have these awesome powers and then get either all the girls or that one girl that really matters. Every teenager into games or fantasy stuff, always hade these ideas about what they would do when they would be personally in that game or this story, but with this one super cool power. It's normal, it's bland, it's common place. And I really don't need to read a story of somebody else doing the exact same thing.
