sleepwalker be creature who drain the life force completely out of human to survive . but they can only use virgin ( it not explain why ) . charles brady ( brian krause ) be one such who need to fee his mother mary ( alice krige ) . he go after likable tanya ( madchen amick ) . will she escape . on one hand this be a great horror film . fast pace and plenty of blood and gore and a nice and twisted sense of humor . there be plenty of in joke reference for horror buff ( castle rock be mention once ) . also krause be excellent ( who would have think he could act after return to the blue lagoon ) a be kirge and amick . but i find this film annoy . it be write for the screen by stephen king and it maddeningly vague . the sleepwalker be never fully explain . where be they from . why be they call that . why do the son have to fee the mother . why do cat hate them and can kill them . what be their power after all ( at one point krause make a car disappear and change color and style . ) . why do they need to fee off people life force . why do it have to be only virgin . why be the son have sex with his mom . none of these be explain leave the story confuse . it really too bad because and those question aside and this be an excellent horror film . excellent makeup and special effect too . fast and gory and lot of fun . if only the script be good . also a fairly explicit sex scene between krause and krige be edit ( you can tell ) to get an r rating . i can only give this a 7 .
