The film is divided into eight chapters by eight different directors, each relating to a different Mexican legend or myth.
The directors were then given free rein in choosing a subgenre to create a story involving the legend.
The varieties of the myths and legends range from real "nota roja" ("red note" news genre) to fantasy folk tales.
Five of the directors - Lex Ortega, Isaac Ezban, Aaron Soto, Ulisses Guzman and Jorge Michel Grau[2] - were established members of the Mexican film industry, while the other three - Laurette Flores, Edgar Nito and Gigi Saul Guerrero - were relative newcomers.
Rotten Tomatoes reports that 60% of critics gave the film a positive review.
