I liked Sam, and all the scenes at the wall (and we finally get a sighting of Ghost!).
I was, on the other hand, deeply disappointed in the King's landing stuff. Maybe it was because they had to make room for those exposition scenes with Sansa and Septa Mordane, and Asister Thorne, AND Vyseres, AND Littlefinger, AND Theon, AND, the Kingslayer, AND I'm no doubt forgetting someone ... but I felt that they really gave short shrift to the Hand's Tournament, which is too bad, since it's really the one moment that Sansa's vision of what life at court might be like actually sort of approaches the reality, until Joffrey sends her off with the Hound. Instead, we got one muddy scene and the Mountain killing John Arryn's squire. Alas!
Also disappointing was that the story of the Hound and the Mountain was given by Belysh rather than by the Hound himself, since it is one of the early scenes suggesting his protectiveness and perhaps even love for Sansa. It also humanizes the Hound in a way that he's going to need to have happen if some of the stuff from the books is going to have quite the same impact.
And, finally, I'm disappointed in the tournament because it failed to introduce us to some characters that will be important later on, like Loras Tyrell, Berric Dondarion, and Thoros of Myr.
On the other hand, I did like the Dothraki scenes, particularly Doreah!
