Review of Mermaids: The Body Found

I was watching this special, having stumbled innocently across it late one night, entirely ready to believe in mermaids. Hoping, actually. I made it through the film not quite convinced - the "scientists" were unusually well spoken, and a bit too pretty. The liberal dosing of crappy CGI and government conspiracy didn't help matters, but still, I was optimistic. I googled the main scientist and clicked on the first few links, all of which led to a page claiming the site's content has been seized in a DOJ investigation. What? That's completely illegal (freedom of speech, anyone?) and upon further googling, it seems the fake pages were registered by Discovery around the time of the program's production. Why? Why would Discovery create a fake documentary, and take such care in hiding that is was, indeed, fake (the creators did release a statement/disclaimer that the program was purely for entertainment purposes, but that statement certainly is difficult to find). I just wanted to believe in mermaids, was that too much too ask?! And having my hopes dashed after wasting two hours on an excess of commercials, horrible CGI, and repetitive clips and conspiracy - I don't think I'll ever watch anything produced by Discovery again.
