@yall.theatl.socialOne of the real gems I had missed until recently: Orphan Black. And I'll second the recommendation for Severance.
Here's something nobody has seen, but is sweet despite the premise: Brigsby Bear https://letterboxd.com/film/brigsby-bear/
I think this fits, too: Moonrise Kingdom https://letterboxd.com/film/moonrise-kingdom/ If you have my sense of humor, you'll also find this one rather funny.
