In either case, they're both almost a Cult of personality. The fans are so adorant of their object that they often overlook glaringly evil deeds. At the same time, the level of manipulation exhibited and the devotion demanded by the personality is extreme to the point that outsiders see it as absurd.
Idk, maybe it's just me but I find fanaticism to be very off putting in general. When the idol asks fans to make sacrifices to stay it in their favor, that's when it crosses a line into creepy.
Disney walks a fine line where it expertly cultivates that culture while simultaneously pretending it doesn't exist and remaining open and accessible to everyone.
