Why. Literally why, on earth, are nearly all the main characters alive ? Why isn't the prophecy of Azor Ahai a thing ? Why would the nk raise undeads after they've been killed by dragonglass/valyrian steel ? Why do they use light cavalry to charge directly, in the dark, toward a far, far superior enemy ? While the 3rd episode had some great, aesthetically pleasing plans (ex : the trenches lighting up, the plan where the dragons are between the clouds, the dothraki charge to name a few), so many things make no sense. Many times in the episode, you could see characters (Theon, Daenerys, Jon Snow) getting swarmed by enemies, yet they always were in a 1v1 in the next plan. Like some others said, the show is nothing more but a 6/10 at this point, compared to the 11/10 at the very start.
Oh, and we learned nothing about the night king, but who fucking cares, he's dead haha, right ? What a fucking waste.
