in the vein of survive ( or alive and if you saw it in the 70 like i do ) and the canyon trap human being in unforgiving terrain only to push the limit of survival . there be a couple of really shock scene here and one involve a rattle snake and another very disturb one involve an amputation and but if the kid close their eye for a few minute there isn not anything else that would make this anything but a pg film . some of it isn not very plausible and in fact the entire idea of the heroine suddenly become grizzly adam and fight off wolf with her bare hand and create a stretcher out of thin air and cauterize a wound with a red hot knife and and keep her beauty and sense of humor through it all and be actually pretty ridiculous if you think about it and but it doesn not matter that much represent this be a disaster movie of sort and so do not think about it . it will keep you go and keep you interested and engage and and from time to time it will make you cringe . but and be warn and the end be the anti climax of all anti climax .
