Fuego gives credence to the idea that you will burn (literally) if you commit adultery and that illicit sex between a married man and his mistress must be paid for. … One of the interesting things that separates Fuego from the other ’60s Spanish exploitation films was that it was actually set in Spain and unabashedly Spanish. … While the film is certainly entertaining, Fuego falls in with the tried-and-true narrative of revenge movies with scarred protagonists, which seemed to be the big thing in the early ’60s, with the British version of The Phantom of the Opera (1962), Circus of Horrors (1960) and the Italian La vergine di Norimberga (The Virgin of Nuremberg, 1963) all having the same general storylines … Unfortunately for Fuego, there was little in the film other than Spanish settings to distance it from the others. … The film, with its twists and turns, is actually fun stuff and makes good use of the Spanish locales and the Spanish supporting players.
