This episode provides an excellent ending to the chapter from the second season.
I'm glad Daenerys will be able to move past the city of Qarth. To be frank, I don't think it was the greatest city that ever was or ever will be. I preferred the other storylines from this season. Still, there was a clear evolution with her dragons. A year after being born (for us), they can now breathe fire. Dracarys!
Also, the last frame is quite stupendous! We can finally see the army of the dead. What a great and incremental progression! Their look with deep blue eyes is creepy as hell and I love it.
I give it 7 out of 10. Excellent ending of the second season.
