When a special guest gets to pick this week’s movie, it’s a perfect 80s time capsule with a sad situation on the penumbra of an adventure. But after the Goonies spend a week at the waterpark with Steven Spielberg, a completely different protagonist actually saves the day. What did the 80s contribute to the Commedia dell’arte? Do all Amblin films take place in the same universe? Why doesn’t Astoria have a social safety net? It’s the episode that imagines both its prequel and its sequel.
