Cinema at the global level is majorly made on the theme of good vs. evil. Cinema about superheroes and super villains is the bestseller nowadays. People love to watch a movie in which the characters have some sort of different powers. The villain seems untouchable because of his great power but the hero somehow finds a way to defeat the bad guy and save the world or city from a big trouble. People love to see action with some VFX. Although, not all of the movies have happy endings- there are movies where the superhero has to sacrifice something to defeat the villain but he does it to save the world.
