Finished season 7 today - have to say that while I liked it reasonably well, I didn't enjoy it as much as season 6. Things seemed rushed, twists more or less out of the blue, time is a bit warped, and there was quite a bit of stupidity all around. This season definitely would have needed 1 or 2 more episodes to flow better. There was enough plot to be covered, more relationships to be explored.
Take the stone throwing to show the army that the ice would hold them. Urgh. Take the little time it needed for Gendry to reach the Eastern Watch, send a raven and Daenerys to come flying to the rescue. Then Tyrion really believes Cersei's pledge to help? And the whole Sansa-Arya-Bran vs Littlefinger, I don't know it felt like there was a scene or two missing. What I don't quite get is why everyone should be shocked about the enmity between Sansa and Arya - they were never friends to begin with. So that they don't quite see eye to eye isn't surprising even after all that's happened (maybe especially because all that's happened).
And let's not talk about Jon and Daenerys' scene - it was always going to end that way (and frankly, I don't really care so much about the aunt/nephew-thing, there are worse pairings), but there was no build-up, no chemistry. Somehow, once Daenerys knew her dragon accepted Jon back in ep 5, it was all a question of time. Wasn't there another discussion about Jon's potential parentage in an earlier season? I seem to remember Littlefinger for one to at least suspect, but wasn't there someone else? Varys? Tyrion perhaps, and that's why he's making that face outside the door? Anyway, all that talk about heirs and children... Well, Jon and Dany don't have to fight it out, let their love-child sit on the throne.
Poor Uncle Benjen, just a prop to save his nephews... Good for you, Jaime, finally seeing through Cersei's loyalties (and actually do something about it). What's his reception going to be in the north, especially with the news he's going to bring?
Would have loved to see all reunited at Winterfell (Sansa and Tyrion ought to meet again at some point) for the ending of this season. The Wall bursting works, too, though. Not sure the dragon is beyond help - but at least, build a lance like the one that wounded Dany's main dragon back in ep4 out of dragon glass, and that threat's gone, if Dany and/or his sibling-dragons (or maybe Jon) can't bring it back to their side.
Anyway, I'm looking forward to the grand finale.
