People thinking Game of Thrones is losing its luster because of a 1-2 episode drought is straight ludicrous. All great shows have lulls.
Game of Thrones is so good because of the conversations between people like the High Sparrow & Cersei (glass houses/stones). Reek & Sansa. Stannis & Shireen. Littlefinger & anyone. I hated Jon Snow before this season as an actor, but he's stepped up his game BIG. Think about the parallel stories ongoing right now! Even Roose Bolton is a great actor.
The silence at the end of the episode was deafening. So ominous.
