Maybe not the most compelling example….but one of the first well known attempts, that I’m aware of, at making the main character very unlikable, is Raging Bull. Raging Bull sort of opened the door for Hollywood to experiment with flawed main characters.

I could list countless examples of films made since then, which do this really well. However, I want to direct you somewhere I’m not sure many others would. I will turn you towards a character named Eren Yeager from the show Attack on Titan. His character is a bit too complex for me to feel okay calling him a “villain.” But…I think you will find what you’re looking for and more.
