Curandero: Dawn of the Demon is an odd duck. A Spanish language film based in Mexico rich in Mexican culture, tradition and folklore, yet, filled with gallons of blood and crazy acid-trip type imagery.
The screenplay adapted by Robert Rodriguez (Planet Terror, Machete) and Eduardo Rordriguez, no relation to Robert, it has moments of brilliance with gritty action and above-average gore effects but the storyline drags and never really establishes a foothold of where it wants to go.
A curandero is a sort of white magic practitioner that deals with cleansing areas that have become cursed or deep in black magic. Carlos is the son of a famous curandero and is called into action by the Mexican City police department and Mexican federales when a major drug crime lord begins using black magic to take out his rivals and generally make a bloody mess of Mexico City.
