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.
He is the Mad Titan, thought.
Althought it's kind of weird how no one in those films leaned into that. It's supposed to be a snark fest and yet NO ONE among the heroes took a potshot at his evil and dumb plan???
They did snark at the plan in the most terrible way. For some reason I watched half of the "Marvel: What If"s and the "T'Challa becomes Starlord" one was god awful. Basically they just jerk off T'Challa as the smartest nicest person ever and he's able to magically convince Thanos that his plot was dumb. Then several characters do exactly what you said, take snarky potshots at the Thanos plan being dumb. Which I hate because Disney/Marvel can't take their own premises seriously. You can't set up a sci-fi/fantasy premise then have your characters constantly joke about how dumb the premise is! Just own it!
