I enjoy the episodes, but it leaves a bad aftertaste.
I was genuinely on the edge of my sofa throughout Episode 3, and my FitBit had me at around 100 bpm throughout. That feeling of melancholy afterwards is what hits me the most. The teleportation doesn't bother me. In fact, I would wager one of Varys or Sansa sent a raven to Cersei to notify her of Dany's impending visit back to Dragonstone. That would explain Euron teleporting. He knew and was setting an ambush. We might find out in the coming episodes.
The thing that really annoys me, is some of the writing decisions. Deciding not to show Sansa and Arya's reaction to the biggest revelation in the entire series. How Jon was built up to be the one to kill the Night King (The Hardhome stare, the Beyond the Wall showdown, the entire reason we're lead to believe he's been brought back to life), but no Arya comes in and snatches the kill. The complete lack of plot behind the White Walkers. The 'embodiment of death' bullsh*t doesn't wash with me, especially when you see white walkers show mercy, and the wights show empathy for their fellow comrades (trying to free the captive in last season etc).
Shall I go on?
I'm tired of people asking others to stop being critical. I f**king love this series and I've been in love with this story since I first read Game of Thrones. I'll enjoy the show, but I won't pretend I'm not disappointed with the direction they're going in and some of the plot decisions they've made.
