The wall climb was the biggest thrill of the episode. Too much time spent on Cersei's and Tyrions marital woes. I don't know that the squibbling between Osha and Meera is leading to anything or not. If not, it's just plain irritating. The Freys were sufficiently creepy - much how I had imagined them.
Theon's torture is getting hard to watch. I had wondered how graphic things might get.
I liked the little voice-over soliloquy by Littlefinger, but all-in-all probably my least favorite episode of this season so far.
