"Everyone loves a hero, but let's face it, the reason many movies are our favorites are because of the villains. Without a great bad guy for the heroes to go up against, a film can seem undramatic and uninteresting, and while some big stars are reluctant to be overshadowed by a villainous performance, the smart ones know that their roles are enhanced by a worthy adversary. The rise of the superhero movie and the return of Star Wars continues to prove this--complex, fascinating characters such as Thanos, Killmonger, and Kylo Ren are every bit as interesting as the more traditional heroes they face."
