without a doubt and bava leave his mark on popular cinema with twitch of the death nerve . it be one of the early lasher i have ever see . the best thing about bava classic be that it start out in traditional bava fashion a a sort of gothic piece and then it generate into a much more modern feeling horror film with kid at a lake be hunt by a psychopath . the blood flow in this one and probably bava most gory . it ashame that he do not make more like this and but i think his talent be actually the old school horror piece like blood and black lace and which be actually an even early slasher from bava . the difference be that blood and black lace lack the theme that be now so popular and with kid be stalk and hunt . that be where twitch win the crown . with all there be to love about this awesome flick and i still have to gripe a bit . the end be a little vague . i be still not too sure what happen and but the twist only halfway work . still though and twitch of the death nerve be a must see . positive and kid .
