Critic’s corner

Another week, another telegenic science guy with a new cable docu-series. This time, it’s biologist Pat Spain, and he is searching for mythical creatures in the wild. He’ll travel to exotic areas, talk to locals about their eyewitness accounts, and interpret the anecdotal and scientific data. First up, Spain goes to the jungles of Sumatra to verify the existence of an ape-like animal that walks like a human. The locals call it the “Orang Pendek,’’ or the little man of the forest. I call it Charlie Sheen.
