Essentially a light-hearted film, Labios rojos mixes frivolity with film noir to create an amusing but not entirely convincing cocktail. … The chief pleasures of Labios rojos are its stylish, sometimes clever photography and its bird’s nest of double-dealing intrigue. … Ultimately, though, neither the trickiness nor the noirishness are quite enough: Labios rojos may be busy and fleet-footed but it’s too detached to really fly. What’s lacking is that essential Franco ingredient, eroticism, making this a cute but slightly arid version of an idea done much better a few years later in the sexier Sadisterotica and the loopier Kiss Me Monster.
