Maybe I am just am ignorant American, but Joe is Johnson at all comparable to Trump in terms of overthrowing democracy? I don’t recall anyone storming Parliament or Boris claiming any elections were rigged.

I think both Darmok and The Inner Light from TNG would be solid candidates. Both are more about the story and dialogue than the setting, and while both have more sets than OP’s examples, there’s also plenty of room to consolidate and move scenes around. Almost all of the stuff on the planet in both episodes, for example, could be a single set with just a few pieces of furniture (or rocks) moving around to give the allusion of location changes.

They are also very good episodes that have a message beyond just the setting and plot, which make for a good play, as well.

Most restaurants in America as they exist now should not exist. We’re essentially all subsidizing low quality, frozen food.
