Eh, its mostly not my kind of stuff. I know Game of Thrones is big, but I didn't like the first book when I tried to read it, I'm not into stories that are overloaded with evil people and situations and don't balance it out with something likeable. I also mostly like Sci Fi and fantasy stuff, which (outside of GoT) those channels don't really do, and the non genre stuff I like is also not really something one of those channels would do. A quick look on wikipedia (for the list of TV shows networks like HBO and showtime have made/currently make) confirms those networks wouldn't be for me even if I didn't object to the rampant nudity in their television shows. I'm not saying they're bad, they just aren't the kind of channels that produce stuff I'd like to see.
