Has AMC lost its purpose?

Sometime after host Bob Dorian retired his leather chair, American Movie Channel began to deviate from its “classic” formula. First came the commercials. Then the movies changed from film standards to popcorn fare from the “Porky’s” era. After that, AMC began airing its own original programming. But at least shows like “Movies that Changed the World” were about film, and classic films at that.

Tonight’s AMC introduces “Hustle” (9 p.m.), a slick and stylish BBC drama about a team of British con artists and the police team on their trail. It’s a fun show with a great cast, featuring TV legend Robert Vaughn (“The Man from U.N.C.L.E.”). Boasting a cool jazz soundtrack, it’s smart and engaging and three times more interesting than the recent “Ocean’s 11” remakes – including “Ocean’s Twelve” (7 p.m. today, HBO) – that appear to have inspired it. But what is it doing on AMC?
