Has a series ever genuinely changed your perspective on something?

I can’t think of a series that has completely changed the way I see something, at least not off the top of my head.

There have, however, been individual films that have stayed with me for quite a while — The Pianist, The Hunt (the Danish one), and a few others.

I’ve actually got a rather long list of films I’d recommend if anyone’s interested, so I might post that at some point.

But I’m curious about everyone else: has a manhwa, manga, anime, book, film or series ever made you genuinely rethink something you believed before?
