Having a rough week with the kids? I know a mother grizzly bear that would be happy to trade places. "Bears" features a grizzly named Sky, who travels from snow-covered mountains to salmon spawning grounds, protecting two cubs that we're told each have a 50 percent chance of dying before adulthood. The cubs are used almost exclusively for comic relief - every scene as precious and whimsical as the posters on the walls of a children's dentist office. "Bears" continues the unfortunate tradition of interpreting animal behavior in human terms.
