I liked the episode. What was most disturbing for me was Roose Bolton, the terrifying, sinister, violent, treacherous lord of the dreadfort being played by Michael McElhatton who I best know for his role of 'Rats' in the series "Paths to Freedom." A worse fit, I cannot imagine. (I don't mean he's not perfect for the part, just that it's hard to make the leap from that character to Roose Bolton) For those who have never seen "Paths to Freedom", see here You might need to skip to about 8:00 to see the full context.
