Jordan Peele fans who go to his latest film “Us” hoping to find another “Get Out” may be disappointed: Where Peele’s directorial debut lent itself to straightforward political allegory, the follow-up feels murkier and stranger. “Us” is a nightmarish journey into a world invaded by sinister doppelgangers. The film does, eventually, offer a rationale for what’s happening, but the surreal imagery (and the unsettling work by the cast, led by Lupita Nyong’o) will stick with you in a way that the explanations do not. On this week’s episode of the Original Content podcast, we’re joined by Megan Rose Dickey to review the film.
