I honestly think HBO or Showtime might be the way to go. In general I have been impressed with the quality of the original programming on both networks.
And I think it would be good for the network because they would have a huge spike in subscribers.
I agree with your analysis. Although, I have to admit that I would prefer Showtime over HBO. Overall, Showtime seems more dedicated to allowing their series to blossom, and become truly entertaining shows. Although, I love me some True Blood.
I agree about showtime.
And, conveniently, showtime is owned by CBS, I believe.
