Jonathan Holland of Variety considered that the film——"a too-rare incursion by Spanish film into the coarse realities of multiculturalism on its cities' outskirts"—features "a crudely makeshift feel that suits its subject".[6]
Irene Crespo of Cinemanía rated it 3 out of 5 stars, considering that Zannou, "with few resources, without professional actors, but with a lot of enthusiasm, and at a rap rhythm", managed to craft "an undeceptive portrait of the reality of any city's slums"[3]
