Season 3 Episode 5, "Kissed by Fire"
Actually, I'm going to write about two of my thoughts on GOT up to this point. Two complaints, really. (I do like the show overall.)
First, the sides competing for the throne are unbalanced. Daenerys is too strong to make that interesting. She has dragons, a super-trained army, and I haven't seen her make one bad decision as leader so far. So unless she made one in season two (which I haven't seen), she's set no precedent for making mistakes. She's more of an icon than a real person. The only obstacle preventing her from taking the throne is her distance from it. The biggest thing going on is us waiting for her to get there, to finish her road trip. This makes Rob's concerns about winning the war seem small. He's only fighting to be interim monarch. I feel like the only thing to thwart Daenerys is either some act of god - flood, accidental spearing - or the White Walkers descending upon her. If it's the White Walkers scenario, then, in the meantime, we're still just waiting for the big players to get somewhere.
And I had something else...
Oh yeah, this last episode was dangerously close to being just a collection of scenes. Some of the scenes survive alright - Papa Lannister telling his adult children who they have to marry, Jamie and Brienne in the tub - but others don't. John Snow's and what's-her-name's sex scene in the cave felt supremely unimportant (even though he was breaking his vows) because their through line has been so spotty. We haven't seen them together since maybe the first episode. We've lost the sense of their romantic tension, and so we don't feel the pay off. They're still an entertaining collection of scenes, but if they lose those through, lines it's going to be increasingly difficult to keep those scenes feeling important.
