Where the evil villain will go on a rant about how society is cruel and needs to change and that they're going to change it. The hero opposes this for like zero reasons and somehow we're supposed to be on the hero's side.
Are we really supposed to believe that our society doesn't need to change? Are we supposed to cheer for the status quo even when it's shown to be terrible?
I also hate the sympathetic villain trope where it's shown that the villain is the product of abuse and yet their want for revenge is still treated as unjustified.
I've not read an entire Discworld book. I know that logically they must be good. People I know who have decent taste in literature speak highly of the series. Every time I crack one open I feel like I'm reading somebody who wants to be Fantasy's answer to Douglas Adams and it grates on me.
