Game of Thrones Thoughts
So having a few days to think on it...I actually liked the last episode. Especially if you read the books the seeds have been set for awhile...although I still think Arya should have died...bear with me on that.
The wrap up for Sansa, Tyrion, Bronn, Bran, Jon and all the rest (minus Arya) was well thought out. It was clear they sat down and gave time and consideration for all the characters involved.
That being said, Arya should have died. Her whole arc has been her not really fitting in with anything. She was too rough and tumble to be a lady, she was too wild to be a Stark, she was too proud to be a Faceless man. In the books it goes very deep into the fact that when she dreams she worgs into Nymeria (her direwolf released into the forests) and there is a LOT more about worging in the books. One of they key things that is hammered on is when a worg dies they can live a "second life" in their chosen animal. One of the Free Folk shamans does this. When his body is killed his spirit lives on in his pet eagle.
This all kind of points to Arya dying and then living on as Nymeria, queen of the wolves! Given how absolutely little she did after the Night King I think it would have been much more fitting for her to suffer a mortal wound killing the night king.
She can do her leap, he stabs her but before she turns into a wight she stabs him and then she too shatters into ice shards. Losing Arya to kill the Night King would have made the fight have heavier stakes. He's the big bad for thousands of years but can't break plot armor?
So in conclusion here is my list of characters handled well, imo:
Sansa, Bran, Bronn, Theon, Jon, Brienne, Grey Worm, Davos, Melisandre, the Hound, Sam
Characters handled so-so (they had their ups, they had their downs)
Varys, Tyrion, Jaime
Characters handled poorly...their arcs really were a let down
Night King, Daneyrs, Cersei, Eunan One-Eye
