Owen Gleiberman Chief Film Critic For more than 40 years now, moviegoers have lined up to see the spectacle of people being slaughtered by a psycho with a chainsaw, a psycho in a Halloween mask, a psycho in a goalie mask, a psycho with burnt skin and a striped shirt and fedora, or a psycho with S&M nails in his face. So why not a psycho Winnie the Pooh? “Winnie-the-Pooh: Blood and Honey” raised a few hackles — otherwise known as free publicity — for having the scuzzy temerity to take a couple of beloved children’s characters and place them at the center of a slasher film. Yet the stunt concept was about all there was to it.
