Apple TV. So good. Just as good as everyone keeps saying it is.
Some people have, apparently willingly, undergone a medical process to segment their memories, splitting their work and personal memories. Their in work and out of work personas, their Innie and Outie. Outie steps into a lift/elevator, and they change. No messages are allowed to pass in either direction.
So, the innie, who we mostly see the stories of, has no idea who they are outside work, or what they do. And outside work, the outie has no idea what they do all day at work.
Add in that the work they actually do is really weird and inexplicable, and give everything inside work a strange and creepy vintage style, and there's a very intriguing setup. Hopefully the payoff is going to be good, but we're probably a long way from actually finding out what's going on so far.
