Bigfoot in search of the truth

There are some fascinating eye-witness stories in this that I haven't come across in other Bigfoot documentaries. Some of them portray Bigfoot as a benign protective being that smiles. The creature that appeared to be protecting a woman's property in Tennessee is particularly interesting. In turn some eye witnesses seem to want to protect Bigfoot and are careful not to give information that might endanger the creature. More is spoken of in this as Bigfoot appearing as a shadow. Another piece suggests that the creature is able to stand extreme weather condition of cold and heat. There is also a suggestion of the creature being the result of a Government experiment which very rarely gets a mention. In fact this documentary expands on the possibilities of what Bigfoot could be but in only byte-size pieces. I say this because with a running time of only 63 minutes there is no room to enlarge on any of those possibilities. The music loop becomes very insistent like some subliminal message help tape that keeps droning on. But generally I think Bigfoot fans will enjoy this documentary which will widen the mystery of the legend even further for them.
