Ok. Your preference is your preference - and I don't think anyone's going to suggest that you shouldn't watch X-Men if you want to. At the same time, one might reasonably read your comments and come to the conclusion that nuanced stories are better than ones that are not.

There is evil in the world. Auschwitz was evil. The Famine-Genicide in the Ukraine was evil. The Gulags were evil. The death of (tens of) millions of Chinese during the Great Leap Forward was (the result of) evil. One could go on. Many people, and I'm one of them, would reject any nuance that tried to diminish and explain away these evils. Do I want to understand what I can do to prevent them? Sure.

There should be room for both nuanced stories and grand narratives.
