This film is a parody of the very popular television series, Digging
for the Truth, which is broadcast by the History Channel. The
episode parodied is Mystery of the Anasazi. In this light-hearted
commentary, Bradley Garrett and Adam Fish highlight certain
superficial aspects of the television production and question its
authenticity and authoritativeness. In the process of poking fun,
they allude to issues of concern surrounding the presentation of
archaeological knowledge through the style of modern day popular
television.
Admittedly, I haven't watched the whole thing, just the first 1/3 or so. I just give this one an "Eh."
