What a dreadful waste of time this series is. It's right up there with the show several years back when Geraldo Rivera wasted hours opening a safe from the Titanic, only to find nothing in it.
It there truly was a Race of Giants, as these two brothers claim, with tombs and burial mounds all over the USA, then why can't they come up with as much as one damned skull to prove their hypothesis ??? They try to give their theory some kind of basis by linking it with Biblical myths about the Nephilim. What will their next series be? Finding Noah's Ark ???? And the acting is dreadful as well. When they are being told of some bone fragment found 50 years ago or viewing some lame rock carving their eyes are all bugged out like Japanese fighting fish.
They don't stay in one area for more than 15 minutes, but just hop from state to state and back again, confusing the heck out of the viewers and making totally baseless claims. All they need find is any kind of circular marking on any stone and it's automatically proof that Sun Worshipers were there 65 million years ago. And so what if they were. It still doesn't prove that they were giants.
Then they show you all of these supposedly sophisticated petroglyph's that look like art work from a kindergarten. These are hardly anything like the beautiful Lascaux Cave Paintings in France.
When all is said and done, they never find anything !!! I am amazed that they found sponsors !!!
