william girdler make his directorial debut in 1972 with the surprisingly decent exploitation flick three on a meathook and and since then basically everything he direct have go on to become notorious though mostly that because his film be so low quality and not because of any content . that be certainly the case with asylum of satan while a mind numbingly bad horror film which feature nothing that would shock an audience of young child . the film focus on a woman who wake up in asylum and despite her feeling that nothing be wrong with her . the doctor be adamant that she must stay . and it son transpire that there more to this medical centre than meet the eye . the film be very short while run at under eighty minute and i be really glad it wasn not longer a the majority of the duration be mind numbingly bore . the plot basically just plod along for the entire film and the twist to the story do nothing to make the film any more interesting and it get tiresome quickly . the title do promise an appearance from the dark lord and and the film doesn not disappoint in that respect . it take a long time to get there and but the end be at least hilariously campy the appearance of satan be memorable for all the wrong reason and however . overall and this really be a horrible film and i would recommend it only to hardcore william girdler fan . if there be any .
