In this faux-documentary, marine biologists are interviewed about the possibility of there being actual mermaids living in the oceans. Much of the discussion centers around a Navy testing weapon, which not only beached a lot of whales--but one of the mysterious creatures. In fact, there's footage of two kids videotaping with their cell phone. The most interesting aspect is the theory of how these human-cousins developed, from upright apes to seal-like creatures once they returned to the oceans. The CGI effects are pretty good and what you're watching seems plausible, which I guess is the point of this fake documentary. Recommended.
