I do find it a little ironic that this "unpredictability" became so contrary long before they left the books it was a predictable institution in and of itself. Oberyn was never going to win that fight, because it was written by RR Martin. Did not need to see the episode to know, lo and behold, predictable again. That last thing that was genuinely surprising to me was the annihilation of the Tyrells. You might have known it was coming but not like that.
So leveling the place and having him surrounded by white walkers who are almost unkillable after everyone outside was dead was in harms way?
I have the same issue are most people with the current writers but the comments in this thread do make me think that they are at least half decent.
