another highly entertaining sci fi film base on a philip k. dick short story which i have subsequently read while and i agree with other reviewer that the movie be true to the story for the most part . have yet to view a movie base on a dick story that wasn not enjoyable and e. g. and blade runner and minority report . if you like either of those movie and you will enjoy this movie for it intelligent entertainment . weller character hendricksson be fairly straight forward a a disenchanted commander believing that his command have be abandon and that their battle on this outpost planet have be make irrelevant by the high authority . consequently and hendricksson set out to bring a truce proposal to the enemy force . but technology go awry rear it ugly head in the form of self manufacture kill device know a the screamer name for their high pitch sound just before they slice and dice human .
