About the only part of the episode I truly hated was the pointless and inexplicable "symbolic" throne melting. I mean, "you killed my mom and I'm so angry about it I'm going to blow fire in that general direction until I see a chair melt" was the best they could come up with?
And while Dany's death was a bit anticlimactic, it was the only way that really made sense. She's followed by armed guards literally everywhere else she goes. While I wouldn't have put it past the writers, I don't think we realistically could have expected another "surprise mothafucka!" from Arya flying out of nowhere, or her and Jon trying to duke it out in some epic battle. It was befitting - the throne was, quite literally, at the tip of her fingers and taken away from her, while all of her supporters got equally shitty outcomes. Granted, Tyrion's job was probably more wanted than not, but Jon had to go skulk off somewhere north, Grey Worm will forever be a lifeless, miserable douche, and the rest of them are all dead.
Bran being king became an "it was so obvious I'm surprised I didn't think it would happen" type outcome, but also made the most sense.
It definitely wasn't the best/most exciting episode, but I think it was far from the disaster that everyone is claiming it to be. I honestly really like probably the first 20-ish minutes of the show, with the really dark tone it set.
