It doesn't matter whether he's fighting Aztec mummies, robots or vampires, I find Santo's movies extremely tedious; The Vengeance of the Vampire Women is no exception.
Mad scientist Igor Brancov (Víctor Junco) resurrects long-dead vampire Countess Mayra (Gina Romand) so that he can use her blood to make his creature Razos immortal. Once back from the dead, Mayra sets about building an army of vampires and tries to kill Santo, who is the last living descendant of the man who staked her.
Most of this film comprises of characters driving from one place to another or of Santo fighting, either in the ring or against the baddies, and it's all very repetitive with little in the way of plot development. Director Federico Curiel pads out his film with visits to a cabaret club where go-go dancers gyrate in bikinis, and adds more sex appeal with pretty reporter Paty (Norma Lazareno), but as much as I appreciate this, the film is still a struggle to sit through.
Santo appeared in over 50 films during his screen career, but I get the feeling that if you've seen one Santo movie, you've seen them all.
