this isn not one of those review about poor special effect or technology and or be date and issue that only the dorkiest people could relate with and but rather a review on the story telling and which most of u be truly interested in . the plot be about a combination of wwii ally and german navy member and and two civilian ( the hero and heroine ) and who be thrust together on a german u boat and wind up in a savage land of dinosaur . the manipulation aren not so bad by film standard and and we know from the plot that realism isn not go to be high . what film like this need be credible and likable character and along with some semblance of reason in the action . this film lack both . for a full length film and only 6 character be give any time and and 3 of them be barely look into . mcclure hero be beyond routine and and doesn not make much sense in any era . the female seem to be look for an answer to a riddle about the land of dinosaur they enter and but the riddle be not much of a riddle and and we could care less . a lot of failure in a film that should have be good and even for it time .
