I agree, somewhat but I think we can all agree that their are different levels to this. HBO and Showtime are one level of what you can do, FX,AMC is a notch bellow that and, USA,TBS,Sci-FI are bellow those. CW seems a notch lower and then at the very bottom you have ABC,CBS,NBC and Fox, though for some reason Fox always seems to either get away with more or simply tries to get away with more than the other basic network channels.
I think it's not very likely this show will feel like a HBO or even AMC style of show. I am thinking more "Sci-FI" channel. People keep wanting to compare it to "Game of Thrones" but I think it will feel more like "Battlestar Galatica" IMO. Dark and Gritty but somewhat tamed down by no graphic sex,pg-13 violence and a lack of extensive cussing. Which is okay IMO but i'm not sure that is what casual fans will want. It can be seen as to graphic to some and not edgy enough to others. Then if it takes itself to serious I think that will hurt if people just want some escapism fun, which usually means lots of humor and fun violence as oposed to graphic and depressing violence.
