Imma keep it real with you, I've been watching weekly and I don't think this show makes for a good binge. There's WAY too much information moving WAY too fast to watch episode after episode with no breaks. I think I've rewatched at least 5 of the 8 episodes out at time of writing, some I've even rewatched a second time.

There are some callbacks that are easier to spot if you watch them close together, but I would still say you're gonna get whiplash by how quickly the show moves.

Ghost is meant to be your soul. That unquantifiable part of you that makes you human. The shell is just meant to be a cybernetic body.

So a Ghost in the Shell is a person's soul/spirit inside of a robot.
