All 3 Tyrion scenes were great, I actually enjoyed the Bronn dialogue over the Oberyn scene. Arya/Hound scenes were great as usual.
Dany storyline is always boring because its so disconnected from the stuff people care about. Nobody gives a shit about the slave cities or the masters and what happens to them. Daario casting is awful, he couldn't be less charming or interesting. Just incredibly dull.
Gregor Clegane introduction really let me down. From the casting photos I thought they'd done a good job, as did most people. But he just came across as a large child to me, he looked retarded in the first shot of his face. His swordplay skills were atrocious at best. His one line had a horribly flat delivery. Nothing about the scene, especially not him killing poorly armed and unarmored peasants, made me feel like this guy should be intimidating. For me they would have been better off letting him be a character only referenced in the conversations of others
But, its a minor and inconsequential scene so whatever. Still the best show going and another kick ass episode.
