LOL at anyone who has truly watched the show and thinks last night's episode was a "waste." It was a terrific episode. For one, it reinforced that Bran and Jaime are the only two who know Jaime pushed Bran out of the tower, and that there is a "plan" for Jaime (likely a sacrifice for the greater good of the living).
One of the biggest takeaways (for me) from last night was further evidence that Dany has gone beyond trying to "make the world better than we left it" and now sounds more like the power-hungry rulers before her. Everything is about "retaking the Iron Throne." This will be her undoing, as I'm now thinking she will not survive to the end. It would have been so easy for her to reassure Sansa that the North would be left on its own after the war. I wasn't at all surprised by Dany's reaction to Jon's revelation -- in her mind, the guy whose family she barbecued and Jon's brother want to undermine her.
As noted above this was a last chance to see all of our "favorite" characters again, because many will die in the episode(s) to come. How can that be "annoying" or "a waste?"
I guess if you only watch the show for the nudity and gore that might be your thinking.
Next week the schitt hits the fan.
