Considering Marvel and their villains.
Their villains were boring not because they weren’t sympathetic enough. You can have a fascinating villains that are evil just because, without excuses. Marvel’s villains were boring because they didn’t put any effort in them.
Why it’s hard for me to respect Marvel is because they don’t really love their own stories and characters and are not interesting in developing them. They are just looking for easy formulas that will help to gather the most amount of money they can.
Loki became popular? He was sympathetic? Lets make our next villains sympathetic then, no matter if that makes any sense or not!!
Thanos could have became a great terrifying villain without all of that
“sympathetic”
nonsense, but Marvel is blinded by that idea of easy formula, so we got what we got.
