I really could not get into SNW. The almost Marvel-satire-level of constant asides and quips takes me out of it. It wants to be a gorgeous, serious show, a wannabe campy homage, and a modern Marvel action-funny, and eat its cake, too.
Contrast to DS9/TNG, where the show is campy but not self-aware, SNW oscillates between winking at the audience and tearjerker storyline in too small of an interval, consistently.
