They say there are three great conflict themes to literature: man against man; man against himself; and man against nature.
It seems to me that Bear taps into two of the three, man against nature, wherein nature is an obstacle to be overcome. and man against himself. Bear always pits himself against nature in every episode.
Ray, however, always seems to live in harmony with nature. And there you have it; one program is filled with conflict -- the stuff of literature (and television) and the other is not.
This is not to say that Bear is "better" than Ray. It is to say, however, that Bear will be more entertaining to more people. Frankly, I vastly prefer Ray over Bear, but I'm not making my judgments on "entertainment" value, but instead, on educational value. i.e. what can Ray teach me today? Plus, Ray's calm demeanor is relaxing while, Bear's frenetic running about wears me out.
Well, that's my opinion, and that, and $4.00 will get you a cup of coffee at Starbucks.
