Santo is a cultural treasure from Mexico. If you have a yen for psychotronic cinema or if you like the underground comic art of Charles Burns then you'll probably love 'em. Keep in mind that these are really fun schlock. The series ran from the late 50s thru the 70s until el Santo died. I generally prefer the earlier ones, but check out the 1966 "Santo Contra la Invasion de los Marcianos" ("Santo Vs. the Martian Invasion"). If you like that one, there has been a ton of DVD releases of the past year or so.
