AMC has "pretty good programmers?" No, I agree they have "mucked up" their current channels. And, I agree with Avid, the Beeb has a lot of great shows that BBCA doesn't touch. They seem to show the dreck, along with US shows with some weak Brit connection (like Star Trek: The Next Generation, a US show with two Brits in the principal cast).
AMC, on the other hand, had a great BBC show: Hu$tle and almost destroyed it. They insisted on "Americanizing" its fourth season. The lead actor quit. The season was terrible. AMC dropped the show. The lead actor came back and they did four more seasons, which AMC kept anybody else from showing (and they did not show it either).
AMC was a great movie channel. OK, Ted Turner locked up Warner Brothers and MGM but AMC still had the rest. What did AMC do to compete? They started cutting the movies and sticking in commercials. TCM showed movies uncut and commercial free.
Cablevision has a history of screwing up their channels. Can we expect them to actually do better with BBCA?
