A fierce analysis of the Horrors of the Market (capital M), exemplified both by the obscene rituals of the Neoliberal firm, with its subhuman imperatives ("networking!", "team building!", the human resources' urge to "role play!" and "scream"!) and the grocery store, haunted by the specter of exploitation. I find remarkable that most American critics completely missed the film subtext. This is a true survival horror.
When seen from the outside, Brazilian film in 2010's reflects drastically changing economic situation & depicts people who are made a fool of by it, for example "The Second Mother," "Neon Bull," "Neighbouring Sounds." So this movie is exactly on this trend, but with Grand Guignol or old-dark-house-ish horror and deadpan humor, is attractively unique. Unexpectable end shouting "Rio 2016 Olympics FUUUUUUUUUUUCK!!!!!"
