That finale was good, but underwhelming. It definitely wasn't the cluster**** I was fearing, but the big moments wound up being anticlimactic IMO. For the unsullied, I'm sure it was terrific television.
First, the positives. The pacing was good and there was some proper closure with most storylines. I liked the merging of the Hound/Arya and Brienne/Pod's arcs and we got a good Hound v Brienne duel out of it. Thankfully, Arya is going alone to Braavos without the Hound after all. I don't remember Bran and co being attacked by those skeleton whuzzits (it was a White Walker/Other in the books), but Bran's ended well. I also liked getting a peek at delusional and paranoid Cersei that we all know and love from Book 4.
Now for the negatives. I was a tiny bit peeved that the finale had one big glaring omission (book readers know exactly what I'm talking about). While on that point, I believe that omission will appear next season albeit it would be less significant IMO (but we have no Coldhands!). Something else bothers me most and that's the handling of Tyrion's scenes.
Up until this point, Show Tyrion has been portrayed as a universally likable character who can practically do no wrong. (Book Tyrion is universally likable but we know he's got issues.) What happens in this episode makes him equally as cynical and disturbed as Arya. One of the most tragic moments in the books is Tyrion's feeling of betrayal by his entire family. Yes, that includes Jaime, when he reveals that his first wife Tysha wasn't a whore at all, something Tyrion finds unforgivable. What he does to Shae and Tywin, he does out of pure rage as a result. Granted, the Tyrion/Shae dynamic is different and his relationship with Shae is closer to Tysha. Regardless, I felt his scenes lacked the power and emotion needed. It also doesn't achieve in making Tyrion more screwed up than he lets on.
Poor Jaime. Revealing the Tysha bit also changes his character, in an indirect but significant way. I would have thought that Tyrion's unjust sentence would be the final straw in Jaime resisting Cersei. Instead, he's still weak in caving in to Cersei and still not keeping to his kingsguard vows. No one will tell him that Cersei has been screwing around with Moon Boy (no spoiler, Moon Boy isn't even in the TV series).
I wonder if D&D have an irrational hatred of Stannis. They spoil Stannis' showing up to save the Night Watch's bacon in the teaser (and in the Season 3 finale). Even then, he's stripped of his most heroic moment thus far, even if the events remain true to the source material. (I always envisioned it as like the Ride of the Rohirrim in LoTR, with the triumphant shouting of "Stannis! STANNIS! Stannis!") This is the point in the story in which Stannis quits obsessing about his birth rights and finally practices what he preaches: saving the realm (aka The King Who Cared).
Good season all in all, but I would say the last two episodes have been quite disappointing. Entertaining, but disappointing as far as the overall story goes.
