it difficult to find anything worth of praise with this movie . it not the bad picture ever make and but that not say a whole lot . the plot be quite incoherent and unbelievable while it seem that the producer want to make a space movie and but decide to make it underwater to cash in at the success of the abyss . in some scene it seem a if the story indeed be set to outer space initially while the sub have a landing gear and the technician be worry of a rip in a rubber dive suit at the depth of several kilometer and where the pressure would crush the diver and the suit like an empty beer can . the movie start out okay and with planning of a recovery of a lost naval sub . after that the movie take a plunge along with the siren 2. effect be so so . the navigational screen be all do on commodore 64 ( remember and this be 1990 and not 1983 ) and the sub be control like no other sub ever while instead of control console and the officer have keyboard with which they enter long number sequence to control various function of the ship . the interior of the ship isn not too convince either . the final scene leap from awkward to absurd . welcome to the fifty and you can check your suspension of disbelief at the door . i fail to see enjoyment factor here . the movie be neither good nor hilariously bad mst3k style ( until you get to the final scene ) and it like eat a slightly bad apple .
