for some reason i like this film when i be young and but now i can not imagine why . the dialogue be incredibly corny and and the character be far too cliche . the film start off fairly slowly and with only minor comic relief from dennis hopper . it do pick up in the last half hour and but the special effect have age significantly over time they be really cheesy and especially the dinosaur . i do not really find any of the main lead likeable either they be all fairly irritating and seem to act in a way which seem in contrast to the character they be mean not to be play . this be probably the bad of the eighty high school or teen science fiction tale and we all know it be make in the mid eighty but do they have to make it so obvious . the story wasn not so bad they just need strong character and good dialogue etc . unless your a fan of bad eighty teen film ( and there be a lot of them ) stay clear .
