Action-wise, incredible.
Character-wise? Total bull**** in terms of where certain characters are ending up / going.
They spent 7 seasons building Daenerys up to be the breaker-of-chains, champion of the oppressed, so she gets mad and flips to commit total genocide because Missandei gets killed?
And speaking of Missandei, she was the freed slave who dies in chains, cool...
They spent 7 seasons building Brienne up to be this total bad-ass independent female knight and the last place we saw her was crying as her man left...
And where did that man go? To kill Cersei which would have been the ultimate finale to his character arc? Nope, he went back to her after 5 or 6 seasons of us thinking that he really wasn't as bad as initially believed, that he was redeemable and honorable on some level.
Meanwhile, those giant dragon-killing Scorpions / crossbows sure went from being super deadly to utterly worthless in a 30 second span.
