Finally watched it, and... a surprisingly low key ending. I was kind of thinking that half the characters would die fighting the other half. I'm kind of relieved that didn't happen - and especially that Tyrion lived!
Jon and Dany - I'd seen a spoiler here, but I think it was clearly expected and even demanded by the story. It seemed a little low impact, but the dragon provided a good finale to it. The surprise was that rather than kill Jon, Drogo destroyed the Iron Throne, which seemed fitting.
Bran the Broken, eh? I didn't see that coming, but then I expected a more traditional story that put either Jon + Dany or just Dany on the throne (or, possibly just Tyrion).
The endings overall seem satisfactory - Jon always wanted to take the black on the wall, and now he's doing what Aegon did before him - the last Targ, leading the Night Watch, with no apparent heir. Unless he really is becoming the King Beyond the Wall, which is even more fitting.
Sansa demanding the North be independent seems a little surprising, but not earth-shattering - I'm not sure why she's demanded that, but it seems a poor consolation for someone trained to be a queen.
Arya - sailing off into the West (another LOTR reference?).
All in all, I think it was simply a relief that
everyone didn't die at the end. I was told to expect something twisty, but I think we got the least twisty ending - especially when these forums have seen so much speculation over the decades, that it's hard to feel surprised by anything (and I'm sure some people flagged Bran as the eventually King).
A bit of an overlong episode, but it underlined that this story was always about the Starks vs Lannisters, something the books seemed to forget but thankfully the TV series got around to.
Btw, I don't understand all the howls of outrage about this season at all.
Now I'll read the comments in this thread.
