"Once upon a time...." Possibly working from Jung's concept of the shadow self (or W.E.B. DuBois's notion of "twoness"), writer/director Jordan Peele unleashes the other side of our selves in this spin on the home invasion horror genre about a family who just wants to spend a nice few days vacationing at the beach. Peele's a master at building suspense. He does it sequence by sequence, each scene in the larger sequence having its own build and climax that compounds like interest until the entire sequence ends with a bang. For example, check out the day beach scene with Moss and Heidecker. Great performance from Lupita Nyong’o, and it's nice to see a Mom lead instead of Dad always being the hero. The only complaint is the current trend in horror with murky villain origin stories, which gets rightfully overshadowed by the searing thematic of of black life being controlled and leading a shadow life, reflecting on the history of film and the larger history of oppression in our country.
