8/10 The episode had some great story lines like Arya, Brienne and Hound, Jon and Daenery's ones. Others had some problems, though. Overall it was a good episode but not a grand finale for a season.
I gave it a 9/10 score. It was almost perfect, with good special effects, nice dialogues and Jon Snow being the badass we know he is in the books. The only reason I didn't gave it a perfect score was the limited screen time of Ghost.
