If you haven't seen this you are missing out on one of the most significant documentaries of all time. It is truly amazing in that this clearly shows the intelligence and capabilities, including the emotional suffering of these "people". Sad, shocking, hysterically funny with the most unbelievable footage ever captured from the Gombe. An absolute must for every man, woman and child. This was actually taped over the period of nearly twenty years, an outstanding accomplishment of the lives of the chimpanzee and the effect of man and the industrialization of underdeveloped countries. Something that needs to be in your collection, even if you don't have documentaries. Teachers, a must for your science students!
