[5] The main actors, Jana Raluy and Sebastian Aguirre, recreate "desperate characters" without exaggerated gestures and postures, "enhancing their work", according to Columba Vértiz de la Fuente of Proceso.

[1] After this premiere, Boyd van Hoeij of The Hollywood Reporter wrote on his review that the film is "a lean and efficient mix of thriller, drama and socio-political commentary", and also praised the leading work of actress Jana Raluy, stating that she "displays the right mix of craziness and steamrolling strength to appear dangerous, even though the awkward way she holds a gun clearly indicates she's a fed-up hausfrau reduced to desperate measures, not a trained killer."
