I mentioned a love for Shakespeare in a footnote, something I developed long after high school, despite-not-because-of my high school education. I found my way into it via movies. The same happened with Jane Austen, whom I hated as dumb-people-doing-dumb-things until the right film showed me how it actually was supposed to work.
Conceivably such a thing could exist for Confederacy of Dunces, but I'm not going out of my way to find out.
But to your basic point. I was having a conversation with a college friend about series including Orange is the New Black and others that I don't remember--possibly Breaking Bad. And they just couldn't get into a series where you were supposed to sympathize with people who were basically, well, bad to various degrees. Probably (for whatever reason) some people just don't like anti-heroes in literature or video.
I don't mean to oversimplify; both are complex shows with extraordinary feats of writing and acting. But I felt Better Call Saul was a more interesting take on the anti-hero because it wasn't just horrible people being mean to each other. If nothing else, comparing and contrasting the differences is a good exercise.
And I was left wondering whether the two groups of people have had different life experiences. Some have had bitter experience of awful people and it'll never be something to enjoy.
