NANCY Those lyin’ Buscemi eyes.

Itโ€™s impossible to describe the titular character in Nancy, writer/director Christina Choeโ€™s feature debut, with any degree of certainty. Everything about her life is shapeless and fluid, filling whatever void itโ€™s invited into: The 35-year-old Nancy (Andrea Riseborough) works as a temp and still lives at home in small-town New Jersey with her ailing, overly critical mother (Ann Dowd). She spends the rest of her time and energy maintaining several different online identities and telling lies about vacationing in North Korea and being pregnant.

Both Nancy the person and Nancy the film live in a vacuum where it doesnโ€™t actually matter whatโ€™s true and what isnโ€™t.

Nancyโ€™s elaborate lies make her seem untrustworthy, but never maliciousโ€”maybe she thinks her stories are true, or maybe theyโ€™re embroidered half-truths. But the stakes are raised shortly after the death of her mother, when Nancy sees a news segment on TV about an older coupleโ€”professor Ellen (J. Smith-Cameron) and psychologist Leo (Steve Buscemi)โ€”whose daughter disappeared 30 years ago. Nancy does the math, compares her own features to the artistโ€™s rendering of the missing girl (sheโ€™s got Buscemi eyes!), and becomes convinced that she was kidnapped as a child and these are her real parents.

Nancy is being sold as a psychological thriller, and while thereโ€™s some extremely subtle suspense, and while Nancyโ€™s meeting with Ellen and Leo certainly breeds some uncomfortable tension, the plot is really fueled by all three charactersโ€™ desperation for and fear of the truth. But theyโ€™re reluctant detectives: At one point Ellen explains, โ€œPeople get taken from you, just like that. We have to appreciate what we have now. Itโ€™s the only thing thatโ€™s real.โ€

So instead of searching for concrete answers, both Nancy the person and Nancy the film live in a vacuum where it doesnโ€™t actually matter whatโ€™s true and what isnโ€™t. The focus is more on the sadness that inspires people to lie, both to each other and to themselves. Itโ€™s obvious that something traumatic happened in Nancyโ€™s childhood, and though sheโ€™s a frustrating protagonist, her willingness to shapeshift and become whatever other people want her to be is relatableโ€”she just wants to make sense of her existence.

Yet while Nancyโ€™s drama can feel real and intense, the filmโ€™s ultimately more frustrating than mysterious. Very little actually happens! Sure, each scene is saturated with nebulous subtext, and yes, the truth might be irrelevantโ€”but itโ€™s still unsatisfying for a story to reveal so little.
