Really? I thought this episode was probably the best of the season.
Though overall I'm annoyed at how long it's taking for some of these stories to happen. WE knew some key storyline and the direction they were to go this season and 6 episodes in we are still waiting tosee Tyrion get to Danerys. Or to see Arya become what she is supposed to. Or to see Stannis do something from the moment he showed up at the wall. Or to see the White Walkers.
If you think you're waiting a long time, you should try reading those last two books.
