It’s relative to the standards set by the show, in this case, GoT set the bar really high and rose to be a phenomenon. Objectively, sure this episode could have rated 7/10 for any other medieval mixed with magic tv show without context. This was beyond underwhelming mishandling of great story, characters, cast, talent and budget. The expectations were extremely high and the show fell victim of its own success. You need to allow people have opinions and stop making it personal. You are trying to act mature, yet to mirror you I could say: “so many braindead kids with no grasp of good narrative, thought that this episode/season was good”. That wouldnt be very mature thing to say, would it?
