In those cases you are quite correct, plus they are on channels that might not exist if not for cable TV. Surely the content of those shows would not exist on broadcast TV.
And that's just two channels out of three hundred. Yes, there are examples of quality but they are severely drowned out by the noise. I guess I should say the average quality of cable TV has gone down over the years.
I suppose if the majority of the channels on cable offered quality entertainment on the level of HBO's or AMC's offerings then my attitude would be different. But since I can access AMC content now with a agreeable arrangement and possibly get HBO's in the future, I don't feel the need to pay for all those channels I'll never watch. Right now I pay for the shows I want to watch.
Plus, Netflix produced House of Cards of which I'd be happy to compare with any of HBO's or AMC's offerings.
