It happens quite a bit. Protagonist privilege gets all the talk in meta analysis, but from my experience in fandoms with bad guy/anti-hero main characters? It's kind of the opposite.

Yeah, I liked Mike (as in I found him interesting) but he was anything but a hero. Dude was going to kill Lydia in her own house with her daughter around.

Meh. Fandoms can be fun, but they can also ruin shows, I think.
