If there was any concern that HBO's GAME OF THRONES was going to miss a step now that it's no longer directly linked to George R.R. Martin's books- having caught up to them last season- that can firmly be put to rest now. The season finale on Sunday, which closed out the sixth run of episodes for the series, was the highest-rated episode of GAME OF THRONES ever, and it topped last year's finale- which held that title up until now.
