I can't decide on what the stupidest part of the ending was, but it is telling i had to fast-forward parts of the episode
Maybe the worst was that the dragon just left, cause it would be convenient.
Apparently the dothraki now are under GW command, cause whatever.
But really there is no point in trying to notice individual issues in such an episode.
Greyworm is executing people, the Unsullied are pumped up, the Dothraki are having a rave...and then Dany dies and the North arrives and there's no real tension beyond Sansa and GW snapping at each other? It would had been well for one last battle to rid Planetos of the zealot horsehockys.
