Now, while I'll be honest when I say the show makes, honestly comical jumps in narrative and logical deduction, and will often turn to an "if-else: "Aliens" situation. I.E. the meme: http://i0.kym-cdn.com/photos/images/small/000/158/329/9189283.jpg?1312526309
But, the truth is, the show isn't all bad. It presents interesting locals, some interesting and 'mysterious' places, some of which are actually quite puzzling. (the famous Zone of Silence, for instance) while others have been explained and the narrative gets puzzling to follow. (The Treasure Pit which is widely beleived to be just a sinkhole by nearly every geologist... could be a Templar hideaway used to conceal and protect the lost arc of the covenent. Which is an Alien reactor.)
Generally, if you come to it expecting some silly stretches and if-else-Aliens, you'll have fun. If you think it's going to be a serious and unbiased discussion, look somewhere else. Also, George Noory is always fun to listen to.
