SERIES PREMIERE: This new nature series spends several episodes in the very small town of Churchill, Manitoba. Its human population is 800 – but as winter approaches, the polar bear population outnumbers them, at around 1000. It’s a confluence of man and animal that’s already been chronicled on TV, by David Attenborough’s The Hunt, but it’s documented very well here also. For a full review, see David Hinckley's All Along the Watchtower.
