The difference between MCU and DC villains.

Another fake complaint.   When it only bothers you when it's Marvel, that means it doesn't really bother you until it's convenient for your agenda.

Or are you willing to say that means Superman, Batman, Wonder Woman and Suicide Squad were not good heroes in MoS, BvS, SS and WW?

This is just turned into a DC fan talking point.  Your sceenname is perfect.

The claim is not even true as proven in countless movies over the years.   Indiana Jones is one of the all time great heroes and has never had a great villain once.    Name one great villain for Dirty Harry.   Superman is one of the all time great heroes and has one of the most pathetic villains....Lex Luther can't possibly present a challenge to Supes.  Some "obstacle".   Let's see you move the goal posts when it's a DC character.

You rightly point out that Vader was the nemesis of Luke in the Star Wars films...

...Guess who was the most popular hero in those movies?     Han Solo.   So much for that theory.
