I have noticed a trend in documentaries over the last decade or so. In many cases, the shows promise all sorts of amazing and earth-shattering discoveries....and really don't deliver. Such is also the case with "Buried Truth of the Maya", a mildly interesting documentary that seems to have a lot of hype...hype which takes away some from enjoying the actual show.
I decided to watch the documentary because I am scheduled to visit the Mayan ruins of Chichén Itzá in a few months. Unfortunately, it really is not a general documentary about the place...but instead follows a few researchers who have theorized that the alignment of El Castillo (the main pyramid) was placed there because of underground rivers that possibly run underneath the place. You see a lot of interesting devices such as ground penetrating radar, an underwater guided camera and more...but you really DON'T see whether or not their theories pan out or not.
Overall, mildly enjoyable but not as amazing as the narrator makes it sound. A lot of hype...too much for a truly scientific examination of these ruins.
