Last episode definitely did not feel like a series ending. So many loose ends, unanswered questions... I feel like there's a few spin offs to be had here. Apparently GOT prequel during the age of Bran the Builder. For sure one with Arya exploring the rest of the world. Maybe one with Bran the Broken governing.
The series ending could have been way better without leading to the spin offs. In this season, it's like all logic flies out the window.
