i also saw this at the cinema in the 80 and have never forget it and even though i have never see it again anywhere . i do not know whether if i do see it now it would seem dated and but remember the storyline and compare it to some of the terrible modern film i have see on zone horror i should think it would stand up very well . i can still remember his coffin slide out and open up and all the dead body become reanimate and and the blue lightning . have see hundred of horror movie and still remember this one and it must be good .
