Presented as a documentary, Legend of Bigfoot is primarily a collection of wilderness footage narrated by animal tracker Ivan Marx. His voice is the only voice you will hear for 76 minutes so I can't really say that this is a fair and balanced presentation of Bigfoot. I will say that he gets very animated when discussing the mythical creature.
Marx's voice is that of an amiable grandfather reading a book to a child. Combine this voice with 70's nature footage and you've got yourself a surefire cure for insomnia. It took me three attempts to before making it to the end while conscious, I'm not gonna lie. At first Marx's voice is charming but after a while you realize that he's one of those guys who just loves the sound of his own voice. I have no doubt he would be really annoying at family gatherings. I suspect that his relatives call him "Irritating Ivan" behind his back.
His quest takes him through Oregon, California and the Arctic Circle. He does capture occasional Bigfoot footage and I must say it's slightly more convincing than those depicted in the other three movies I guzzled this week, but still, ultimately most like a guy in an ape costume.
In conclusion if you enjoy watching 70's gazelles, bears, wild cats, antelope, and don't mind the extended scene devoted to an injured squirrel, then this film is for you.
