Oh I'm sure... but Spartacus seems to be a more lurid show than GoT, everything I hear about that show is sexy sex slaves having sexy sex with the sex and there's also sex, and don't forget the sex.

And frankly, I feel like a show that has background nudity and not main actor nudity is insincere, it builds up false expectations in a way.  It kinda breaks the illusion, if we skirt around Six and Boomer's nudity on the show (and what about Lee? Or Baltar? Where's the man meat?) but show background ladies kitless, it seems lobsided.
