Miranda July is a genre of her own—quite literally—this week on Be Reel. We’re talking about the just-released “Kajillionaire” (2020), “Me and You and Everyone We Know” (2005) and “The Future” (2011). In each, the writer-director introduces us to relationships familiar but strange, where chat rooms, taboos and family traditions both create and bridge the gaps between the world’s loneliest people.
