Review of El Topo (1970)

A black-clad gunslinger takes a naked boy—presumably his son—out into the desert to bury a toy and a picture. They return to a desecrated village and then set out for revenge. Succeeding against the fearsome Colonel, the gunslinger leaves the boy and acquires a girlfriend who propels him onward to fight each of the four great master gunslingers, learning the lessons required for a transcendent rebirth in time to meet the boy again.
