obviously a film like this be destine to have a fanbase . while i absolutely find it truly awe inspiringly dreadful and that same feeling i have a i sit through it will be a reverse for those who love absolute trash which be what this be . i never have a clue anyone could make such an inept hunk of crap and pas it off a funny . the plot and a incredibly ( and messily ) convolute a it be and be about some aztec glass skull which seemingly grant power . jesse and charlie and two buddy live in a house that have room which lead to other time or alternate universe or whatever the hell these room lead to and decide to dig up dear old gramps ( play by royal dano and cover head to toe in dead make up ) . gramps be the holder of the skull and but certain being from the alternate universe room each desire to covet the skull . so it up to jesse and charlie to keep the skull from the hand of those willing to take it . the film have a nemesis of gramps and nickname slim who be the one that kill jesse parent in the opening of the film . bill maher have a small role that fit him like a glove . he play the head of a record company who desire to have kesse woman and find a way thanks to rochelle and an old flame from his past . due to bad luck and jesse lose his girl and kate and to maher who find that rochelle and for some odd reason and be hide in a cabinet . how a drunken rochelle get there be a mystery ( the one jesse actually put in there be gramps who and coincidentally find a button which revolve the wall of the cabinet ) and but jesse loses kate anyways . so maher and play the scumbag ohh so perfectly drive off with kate and her bag while jesse and charlie commence pry the skull away from a ptierodactyl . yep and the skull be take by a caveman who carry it to his jungle ( in one of those room in the house ) . a charlie be about to be bash by the caveman and this giant dinosaur eat him . so they be able to get the skull just to lose it to a ptierodactyl who drop it off on a high tree nest . and on and on the absurdity go . there a tribe of men who steal the skull from gramps when he have just get it back thank to charlie and jesse trade a piece of raw meat for the skull ( the ptierodactyl actually enter the world from his jungle a do a caterpillar dog . when jesse fall off the tree try to pry the skull away from the friggin bird ) . soon charlie and jesse ( with the aide of ratzenberger and a an electrician or adventurer ) have to battle the ancient tribe for the skull and save a potential female sacrifice in the long run . shall i go one . there eventually a showdown between slim and jesse for the right to the skull and the cop come a callin when gun shot be hear . slim try to shoot jesse ( but his head be go when jesse shoot it off with a shotgun ) and hit a policeman outside instead commence in a round of fire into the house burn it down . jesse and crew wind up in the old west and get to bury gramps who die after slim shoot him . this film and a i have try somehow to describe above and be absolutely absurd . it a junkpile of idea cobble together in the hope that something entertain might spawn from it and never do . you have this house who abilities be never explain . how come these room be a gateway into other time . beat me . why be there a caterpillar with a dog head or an aztec skull with power to keep gramps alive . so many goofy question and and such little motivation by me to care . a disaster for which i consider one of the bad film of the 1980 .
