It is a great ending for the Starks. Sansa queen of the North and Bran king of the 6 kingdoms... Until they get voted out I suppose, or another tyrant comes to claim the crown.
To be honest, I still expected Bran's eyes to turn blue until the final credits, as if possessed by the Night King. That would have been a nice cliffhanger, not all fairy taley and rosy with ponies, care bears, hugs and kisses..
I guess not. We'll have to wait for the spin-off to hear more about the white walkers again.
