No ur not, u got it right, but they would have stayed in a loop if the end wasn't like this. He was the only one to take revenge for daddy Stark. Everyone forgot to venge him. Ends are never well taken by addicts and i think we got addicted to GOT any other end would have been predictable, so the unexpected is always the best. A finale Twist of the mind. :p
I love your interpretation, love your enthusiasm and i'm glad we finally had a Show that has ended with no coming back at all. hahaha
