I know the closure scene you refer to-- which made me gag:
When the CIA guy’s MI-6 partner was mind-controlled and kidnapped by the alien ghost-zombie kid (due to her own rampant stupidity) he decides the only way to save her is by having the teenage daughter of the original victim, the grieving mom, talk to her to get her to deal with her grief and find ‘closure’, even though the mom is in some sort of alien coma and nobody knows if she has any awareness of anything.
Daughter: “why do you think this will work?”
CIA guy: “Because it HAS to!”
If this show stays so ridiculous it may become an ironic watch for me, similar to “Under the Dome” when it became so popular they decided to stretch it from a one-and-done summer filler mini-series to a multi-season arc, and the writers had no idea where to take the story once it totally diverted from the book framework.
It was great fun to watch for the last couple seasons: "Hey, the dome is magnetic now, and it crushed somebody between a car and the inside of the dome! Hey, the dome is raining something that looks like blood and burns like acid! Hey, the dome is shrinking and will soon crush us all! Hey, there are butterflies for some reason! I did feel bad for Dean Norris, coming fresh off his fantastic performance as Hank on ‘Breaking Bad’ to get caught up in that epic trainwreck.
