What pisses me off, is that a reputable TV channel, uses the reputation of excellent programs, and IMHO true to the facts, airs this load of flipping rubbish, purposely to fool the viewers.
I must say that I am disgusted with this method of fooling viewers, and was one that was fooled by viewing this program, until I was shown this from snopes, Mermaids: The Body Found

If I was a donor to 'animal planet', I would cease to send a single sent more towards their coffers.

I would have no problem if at the beginning of the documentary, it was stated that it was a bit of speculative evolution, and the same message applied to the description of the contents of the program..
