Watching as I go along with this post.
Joffrey @ King's Landing - Seems like just going through the motions. Gillen's appearance at the end is kinda meh but I'm not too incredibly fussed. Sansa subtly carries that scene imo.
Varys/Ros - As much as I am against them adding useless extemporaneous shit to the show, I found this scene relatively inoffensive. It was an obvious powerplay by Varys against Littlefinger by stealing her from him, and so far anything that pits Littlefinger and Varys against each other is fun as hell. There hasn't been enough of that in the series, I think.
Jaime/Brienne - they've run with a different interpretation of her idea of honour that's slightly less sympathetic than it was in the books. I don't necessarily agree with it, but I respect Bernhoff and Weiss' adaptation of her, because looking from a different perspective I can easily see how they came to that conclusion about her.
Also, I think they just wanted to show her being a badass, but w/e. The look on Jaime's face is priceless.
Robb/Catelyn - Yeah I felt this scene might have been weaksauce. Makes Robb seem incredibly childish, which is an odd face-heel turn given his previous honorable shit. Catelyn has derped a bit in this season, yes, but every scene she has been in makes me love the character more.
Robb's wedding - huge yawn.
Melisandre/Stannis - It's interesting seeing Melisandre taken out of her comfort zone on screen. They could have fleshed out Stannis' moment of doubt/weakness a little better, though. It was the right scene to have post-battle, but they handled it pretty oddly.
Also it makes Melisandre look like one of those dark-side-seductresses. D'you think she gets off on being strangled?
Theon/Luwin - I absolutely love everything about this scene. Everything in this scene sums up Theon Greyjoy and the men he leads and everything he's done this season. He's being utterly irrational and batshit insane, of course, but it's been acted so well it makes him a much more interesting character than he was in the books imo.
The speech was glorious, but the absolute piss-take at the end was even more gold at the end of the rainbow. My favorite scene out of this episode so far.
Luwin/the kids/Osha - pushed all the right buttons, all of them ;-;
Also Theon has the best theme in the soundtrack out of the entire series. Ramin Djawadi has been absolutely on form.
Varys/Pod/Tyrion/Shae: I liked this scene as well, but it was mostly just character interaction, nothing mind-blowing. Shae becoming more sympathetic? I like. It's fun to see Tyrion trying to rationalise her as a whore in order to stop having all them feelings
Tyrion still great as usual, anywho. Scar could be a little more disfiguring? But meh that's just the same conscious decision as they did casting someone as good-looking as Peter Dinklage.
also CMON MOAR PODRICK SCREENTIME PLZ he looks like a cool kid to watch
