I thought that was a great episode. Honestly the only problem I had was with how
episode spoilers (no book spoilers):

the Renly scene was shot. It just looked so...pedestrian. Reminded me waaay too much of Lost with the way the shadow swept into the room. I had hoped it would just travel on the walls, which would have looked creepier imo; like a Dracula homage.
Qarth looked beautiful, and while there still was a Sci Fi channel cheese level, overall I liked the scenes there. Not a big fan of Quaith's mask though; she looks like a gimp or some shit. Pyrat Pree looked awesome though.
In terms of the Arya change that has book fans pissed: eh. I'd imagine "that scene" will be replaced with something else, so I will reserve judgement until we get to that point.
I loved all the anterior shots in this episode, especially in King's Landing (filmed in Croatia). Dubrovnik is one of the most beautiful cities in the world and I'm glad we got to see more of it tonight. The Qarth scenes were shot there too, and they managed to hide it perfectly; it gave me a Babylonian vibe.
Also it was awesome to see Roy Dotrice playing the pyromancer! Awesome cameo, and I loved his interaction with Tyrion and Bronn. Bronn continues to get some of the funniest lines in the series
