I was really impressed by the finale. I agree that the sequence leading up to the Sept destruction was one of the best moments in the whole show. You know something bad is going to happen, and many already guessed it was the Sept bombing, so I was pretty much holding my breath for several minutes in anticipation. A great mood for them to set.
Arya's conclusion was immensely satisfying.
Baby Mormont stealing the show in the North again.
Was hoping Sansa would be Queen in the North, but I think this might be a symptom of book-show dissonance. They are putting the pieces in place for the book finale, but the show's taken a different route with some characters -- so they're wedging those pieces into certain positions. In the books, Sansa isn't as likely to show up during the Retaking of Winterfell due to her ongoing plot in the Vale. Her book plot will likely take a different path. Jon's doesn't deviate quite as much.
The Tower of Joy scene at last. Essentially confirmed, though it wouldn't have hurt to just fucking say it. Kinda wanted to see a flashback of Rhaegar. Maybe next season.
Brienne was just left up in the air (Star Wars filming commitments?). Same with the Hound. Wonder how they'll factor into endgame.
Dany finally fucking sailing to fucking Westeros was satisfying. Dorne can stick around so long as they're her bitch.
Finale definitely set the tone for "the endgame is coming," which is a sensation that the books haven't portrayed so clearly yet. It definitely feels like we're sliding into the end. Apparently there's going to be two more seasons -- but they'll only be 6 or 7 episodes long. Hopefully they're shown in the same year. I'd hate to wait a full year for a half-season. Sounds like the endgame was going to be one big season, and then they just split it in two. The Mockingjay / Deathly Hallows treatment.
Cersei's fucked. Though Dany may appreciate that she's redecorated it in the Targaryen style.
Pretty sure Jaime's going to end up killing her.
Will post endgame predictions another time. But woo! Hope they keep this pace up for the endgame seasons. A lot of dull episodes padded this one out.
