even though the movie basically feature all of the ingredient need for me to enjoy a silly b horror movie and c. h. u. d. just do not do it for me . it have a good concept and at least as good a it can get for some silly b monster movie trash but the movie do very little interesting with it potentially good concept . the first halve of the movie can be basically see a a build up . not much be happen in it first halve but also from the moment one when the cannibalistic humanoid underground dweller show up the movie doesn not really know to become exciting . the movie still succeed in gain a cult status over the year . who know and perhaps if the movie feature some more gore and it would have be a well and also more entertain one to watch . the movie have a quite ridicule story that also isn not be make exactly believable by it storytelling . douglas cheek directing be lack and the movie also make a mistake to feature several very different character and of which the movie loose it focus on from time to time . the one moment the movie be about the daniel stern character and while the other it about the john heard and the other it about good old captain bosch . the movie really lack on good clear main hero and instead the movie focus just a bit on each of them and with a a result that we a the viewer also just do not really ever start to care about any of the character . the movie also isn not help by it bad edit and the movie feature a couple of moment that make you wonder what it be what you be just watch there . the movie just doesn not always flow well and especially toward it end . perhaps the most amazing thing about this movie be it cast . john heard and daniel stern be both respected actor and though they be mostly active within the comedy genre . it make it all the more weird to see them both in a movie such a this one . the movie also feature john goodman in one of his early movie role . it just an 15 second part though but it be fun to see how his career start of for him . play a fat cop who get eat in a diner by cannibalistic humanoid underground dweller of course always look nice on your résumé . amazingly enough the movie in 1989 even get a sequel and though i doubt that this be because of the big box office success of this movie . it do make a profit but with a $ 1 and 250 and 000 this of course isn not very hard to achieve . it budget really show on screen although i must say that the cannibalistic humanoid underground dweller be not bad look . i just wish they be in more sequence and could have add some more tension and horror to the movie . it have some redeeming quality but overall it remain nothing more than a bad and silly and 80 b monster flick . 4/10 .
