By John Keegan and Gregg WrightThis was definitely this season's most difficult episode to review. "Blackwater" was a break from the norm, in that it told a more self-contained story and worked as a climactic season finale. "Valar Morghulis" is, in most respects, a return to the norm. Some developments feel like major turning points and undoubtedly well-suited for a season finale (and we'll discuss that more later), but like most episodes of "Game of Thrones", it feels like just one small piece of a much larger story. It's a lot harder to gauge my personal reaction to something like that.
