Odd topic perhaps, but I just felt like doing it.
My list thus far....
Animal Icons, Godzilla. For obvious reasons.
Animal Planet
Behind the Planet of the Apes, hosted by Roddy Mcdowel.
TCM(I think I have watched this more than the films themselves.

)
Comic Book Superheroes Unmasked.
History channel(If you're a fan of the industry in any form this is a must see.

)
Watch the Skies, a doc about alien invasion sci-fi from the 50s and 60's. This one is new and debuted on
TCM just a couple of weeks ago to capitalize on the new WotW, another great show.
Also, anything dealing with cryptozoology.
How about the rest of you?
