The Ghost Nation episode was excellent. It also conflicted with some of the ideas they established about hosts, IMO, and it was a kind of storytelling they didn't use before or after. That's more of a knock on the overall show, since I would love a version of WW that played more vague and less technical with the level of agency hosts have and left more space for us to project our own humanity on to the hosts. Getting very technical and explain-y with stories about sentience, identity, and agency–much like with time travel stories–actually makes it harder for me to connect to the emotional and human core of the story. Give me enough details to buy the magic and then give me space to insert my own experiences and feelings. I thought the performances in the Ghost Nation episode achieved the effect that they wanted for the other hosts in the main story but have, IMO, failed to achieve because it's become more about the puzzle box and a technical illustration of every decision a host makes.
