The big thing about the show, and the games is the moral ambiguity of it. It’s captured in a line that maximus says in episode 2? Or 3? Where he says “everyone wants to save the world. They just disagree how to do it.” It’s an important line because everyone has their own way of dealing with the wasteland, which isn’t inherently wrong all the time. And if you watch the ghoul, you’ll see there’s a lot more depth to him than being a comedic psychopath. Give it a little more time and you’ll connect with the characters more. Less so with Lucy, but I think she’s there more as a blank slate, to show how the world can change an otherwise good person.
