So the entertainment field has used skinwalkers since 1913, if not earlier. Isn't this a textbook example of an unoriginal concept? How about if we call a moratorium on stories involving Native skinwalkers and werewolves for the next century or two?
Coming up next? Because of a shaman's curse, a Navajo skinwalker entombed in a burial ground returns as a poltergeist but is bitten by a werewolf and assumes the shape of a wendigo before being possessed by a evil spirit housed in an Indian skull and going on a rampage. Only a skeptical sheriff, a beautiful young scientist, and a wise old Native can stop this creature before it kills again. (Warning: If anyone steals this idea and makes it into a movie before I do, I'll be really peeved.)
