The Jackal was a movie from 1997 that followed the villain (Bruce Willis) as much as the hero (Richard Gere).

While the movie had some flaws, especially Gere’s fake accent, I do really like that concept of following a villain as much as a hero. It can work well in a lot of contexts. Has to be the right type of villain though. Complex and interesting, or entertaining.

Arcane did that too, which is part of why I liked it.
