If you have never before seen this documentary type series on The History Channel before you may be doing something wrong. They take history and usually put in unexplained scenarios and attempt to link them to extraterrestrials. A lot of the time it is mind blowing but of course when the shows subject is as touchy as it is you can tell it my be over dramatized. The show has commentators and one specifically has gained a lot of fame from the show (although not entirely positive) is Giorgio Tsoukalos. He is pretty much famous for his haircut and his Italian-esque hand movements when he describes something and it all adds to the show. Overall it is a really entertaining show especially if you believe in the theory of us not being alone (which I do.) Series gets a 8/10 and a 10/10 when you aren't sober or on ground-level.
