it hard to tell if this ham brain b movie adventure be a spoof and a homage or just plain bungled and but it doesn not work whichever way you look at it . base on michael crichton so so novel and it a nutty mixture of lose city and giant hippo and monster monkey and naff visual effect and corny dialogue . the first thing that scupper this tosh be the gorilla that can communicate in sign language and and needless to say the film doesn not get any good from that point on . make all this old rope somewhat worthwhile be tim curry and turning in a feverish slice of ham and sport a bizarre accent that defy identification and and ernie hudson and who also seem to know that this be all a load of old rubbish .
