You know, I wanna like this show, and to an extent, it's kind of fun...but, in order to (I guess) make what they think are more interesting TV visuals, the hosts will take a theory---and then run with it in a direction I (at least) doubt will yield the best investigative results.
Example: If you are trying to ascertain the truth behind the authenticity of an interesting runestone and its unusual, unexpected location in the New World, why then "try to create runes in stone" yourselves? Why not more closely investigate the life and circumstances of the Scandi man who a century or more ago unearthed the thing and claimed it was real? Would that have bored people to death? (Not me: I'd have been fascinated to hear more about him!)
And why "prove you can recreate Viking tools" in every episode when, to me, we could spend more time in labs looking at carbon dating, or in museums/libraries and the like studying with scholars...? Too boring? Not for me. That's the show I WANT to see.
