Won't get into any spoilers, but we're pretty far into Season 4 and nothing has really happened. There's no one we're supposed to be rooting for is there? Dorothy isn't likeable, Sean seems really ignorant and pathetic (instead of sympathetic) and Julian doesn't seem to care about anything.
This episode recycles things from past seasons, remember in Season 2 when Dorothy just kept making assumptions about the church and how if she did what they said it would all work out yet it never did? Here we go again with that nonsense. Also Sean behaves in this episode like he's completely ignorant of Jericho's fate being tied to Leeane. The neighbors and the Party is pretty dull, there's what I think was supposed to be a "Clever" Swerve which doesn't land at all.
What's really frustrating about Sean and Dorothy is they don't seem to consider what comes next after Leeane leaves. Even if they got to keep Jericho (which the showrunners might do as some sappy happy ending with no explanation) they know Leeane has dozens of Followers literally right outside. What do they think those people will do if Leeane is forced out?
Lastly, and this is the worst part, they've destroyed Leeane's character and made her generic "Psycho Obsessed Nanny" which is such a overdone trope... Why does she even care about the Turners at this point? There's no understandable character development.
