Adapting a classic film into a television series is a great idea from a marketing perspective (it’s a pre-sold franchise with name recognition) and a boldly terrible idea from an artistic one. “M*A*S*H” admittedly worked out pretty well, and I still ride for “The Young Indiana Jones Chronicles,” but for the most part it’s a bleak subgenre“Fargo” could go either way: the cast is promising, and with shows like “Louie,” “Justified,” “Archer” and “The Americans,” FX has established itself as a safe home for good and serious TV, but it’s tough to be optimistic. Now you can watch the first seven minutes of the first episode and see for yourself.
