first of all and yes and animal have emotion . if you do not know that already and then i believe you be a moron . but let assume that none of u be moron . we all know that animal have emotion and and we now want to see how these emotion be manifest in nature and correct . what we get instead be a tedious and ridiculously simplistic documentary that attempt to show how animal be human . the filmmaker search high and low for footage of animal engage in human like behaviour and and when it happen they say and that monkey be almost human . ( that actually a direct quote ) . everything be in human term . they waste time theorize about what make dog smile and but not once do they mention what a wag tail mean . the arrogance of these researcher be disgust . they even go so far a to show chimpanzee dress in human clothing and wear a cowboy hat . i have be expect an insightful documentary of animal on their own term . i want to learn how animal emote in their own language . but instead and researcher keep fall back on pedantic and anthropomorphic observation and assumption . add a cheezy soundtrack and image of chimp celebrate christmas and and this be enough to turn my stomach . but it doesn not end there . half of this documentary be film not in the wild but in laboratory and experimental facility . all the camera shot of chimp be through steel bar and and we see how these monkey be crowd together in their sterile concrete cage . one particularly sobering moment happen near the beginning ( though you have to be quick to notice it ) where a captive monkey say in sign language and want out . hurry go . obscure reference be make to stress test and psychological experiment which i shudder to imagine . baby monkey be separate from their mother at birth and be give wireframe doll in order to prove that baby monkey crave a mother figure . and after 40 year of experiment and the smug researcher pat themselves on the back for reach their brilliant conclusion represent monkey have emotion . one chimp name washoe have be in a concrete cage since 1966 for that purpose and and to this day she remain thus . we get a brief glimpse ( again through bar ) of her leaning against a concrete wall with a rather lackluster expression . personally and i do not need to see any further experimental data . washoe and i apologize for our entire specie .
