Cami: Recently I've enjoyed the Shades of Gray Gray Barker doc. You may also want to check out the Is It Real series. It is more from the skeptic's pov but it's still on topics you enjoy.
If you have not seen the Eyes of the Mothman doc. On instant view, you may like that as well. Don't forget The Monster Quest series.
Some others I have found recently:
Pyramid Code Series
Micheal Wood's In Search Of Myths and Heros (of particular interest is the episode on the lost city of Shangri La)
Trinity and Beyond: The Atomic Bomb Movie (narrated by William Shatner)
Andromeda Strain (fiction)
Hope this keeps you busy!
