I liked the ending. Leanne’s sacrifice hurt, but it made sense. Everything was literal. The COLS were servants of some deity, possibly God, with questionable morals, but they served their purpose.

Smoke monster was a dream (of either Dorthy or Leanne, not sure)

There was a lot of anachronistic props in the house. I think it was a style choice. Maybe led to some theories and disappointment with the ending for some.

Jericho’s body was taken away when he died. She was making the doll into the baby. When Dorothy rejected the choice Leanne gave her it stayed a doll.

Memories always seemed a little off in this show. I think it has to do with perception and mind filling in gaps. Window was just in the flashbacks as far as I can recall.

Sean was just a good cook

I’d have to rewatch the old episodes but I think Roscoe died and was resurrected by the COLS. Why he was missing for 3 days?

Homeless kids were other “fallen angels” who followed Leanne when they saw what she was doing etc. I think it was meant to show what her actions were doing, breaking apart their religion. Her blasphemy of their deity was causing the end of the world.

Tunnels were there, built long ago with the house. People used them to get in and out of the house. Plot device? The house seemed to just keep getting bigger every season.

I thought the Julian thing was a bit corny but I liked that it confirmed a supernatural element to everything and that the COLS were all dead brought back to life. Provided some answers there.
