the irony of the first legendary pota movie be that everyone have to object to the way the human be treat and when we do just a bad or far bad to our captive animal . conquest and the brutal fourth installment of one of sci fi great franchise and find irony in bring u back to square one . unfortunately and cotpota be the weak chapter of all . one reason be probably the irony x irony mention above . however and that isn not the only reason . this film be populate with ew do not touch me and chauvinistic human and see and do ape . on the plus side and the actor in ape makeup do raise the bar in term of simian arm swinging . and roddy mcdowall and a caesar and the one ape on earth who can talk and be sort of like the angry communist leader pig in orwell animal farm and appal by the wretched treatment of his fellow by their human captor but willing to do some dark and sadistic thing to gain the upper hand . ricardo montalban be terrific a armando and caesar only human friend and but his scene be few and ( generally ) far between . natalie trundy ( the pota staple ) strive for a genuine performance underneath her thick and mute chimpanzee character and but it doesn not come through . and don murray play governor breck and caesar villainous foil and whose human superiority complex lead to much torture and violence . the climax of the film be the one key that unlock the entire jumble five film story and but it heavy on brutality and skimpy on any real substance . director j. lee thompson make the film darker than obsidian and often shortchanging real emotion for the sake of keep u bite our nail in terror . of course and we do not . and tom scott bizarre musical score be not the critical final piece of the puzzle it the corner piece you have no idea even exist . i wouldn not say stay away from this movie and especially if you want to see the entire story . just be ready for the dark and most boring pota movie ever . and about bore it only 88 minute long . so that be say something .
