First time around I really disliked the episode (not just because of the plot bullshit but also because I couldn't see anything on my new TV).
Recalibrated my TV and watched it again and although I enjoyed it much more on this second viewing due to the spectacle of the battle and some of the character moments (I thought Beric, Theon and Jorah all had decent send offs), I still can't help but feel a little disappointed that the Night King went out like that and that the battle, despite its spectacle, ended up feeling like an anticlimax.
Going into these last three there do look like there are some interesting factions forming? Hopefully now that the dead are done with we will start to see some more backstabbing/maneuvering by the key players now that their common enemy is gone:
1. Sansa, Tyrion, Jaime and Brienne
2. Arya, Gendry, The Hound and Bran
3. Jon, Daenerys, Grey Worm and Yara
4. Cersi, Euron, The Mountain and Tycho (Iron Bank)
