Finally watched it (thanks for the thread title spoiler btw...) and I didn't love it, but didn't hate it. Haven't read any posts from this week, so probably will repeat what most have said already.
Cersei: I was counting on a different death for her, being killed by someone, but the way she dies works fine as well, hugging the only man she ever loved.
Euron: What the fuck was the purpose of this character?
CleganeBowl: Was what you could expect (loved the rag doll Qyburn lol), but it doesn't feel like Sandor won. I know there wouldn't be that many other ways to kill a dead guy, and I get the irony, but I don't think this was a place for irony, it was about beating the bully, making him die in the same way that scarred him for life felt kinda weird (I know, he probably died during the fall/hitting the ground, but still).
Danny: I feel like this is where it could've been done a lot better. I get the full-heel turn, but it feels way too rushed. The problem is she doesn't have any friends left who she can talk to, because a couple of lines would've helped the turn. Also, it's kinda strange to see the damage one single dragon does, when last season (or was it in the 6th? Not that important) we saw 3 dragons struggling to destroy a single ship.
