Loved the direction, especially Arya's POV: 9/11 visuals were strong. Also unlike most people I like the magic horse. I've heard a lot of anecdotes of seemingly weird/ethereal shit like this appearing in the midst of actual combat, so I don't share the same complaints I've seen in that regard. I also really liked the symbolism in that it looked just like Dany's silver horse she received as a wedding gift, but was now covered in blood.
I also thought Cleganebowl was good, particularly the pre-game interaction between Arya and Sandor.
All in all I loved the visuals, direction, and performances all-round.
The writing, however, was trash. They massacred Jaime's arc, FUCK SHOW EURON, Dany's descent into madness was completely unbelievable because it simply hasn't had enough time to develop, Jon is now just a fucking damp squib, Tyrion is a bitch, and Varys is apparently a retard who has his own spies come and knock on his door and meet him in his own chambers? Also FUCK SHOW EURON.
Overall if I had to be objective I'd give it a 7/10. 9 for visuals, 9 for direction, 10 for performances (particularly Maisie), 10 for music, but I'm legit subtracting points for the writing.
In context though, it wasn't 7/10. In the context of this being the culmination of the story arcs of so many brilliant characters over so many seasons, it was legit hot fucking trash 0/10 REEEEEEEEEEE.
