So, first of all ... Awesome!
The final image, Celt, was I think exactly the one you're envisioning -- Dany after the fire with her children.
There's so much to discuss, though it adhered so well to the book (while bringing in a few early scenes from the next book as well) that there was nothing I found really surprising in any regard, but it was enjoyable seeing how they got to that final shot.
So much happened that I was a bit surprised to realize that I had forgotten about Arya for a while after the ending of the episode. But once I remembered again, I sort of wished that they had given us an initial introduction to Jaqen, instead of keeping him covered up as they did.
They're definitely making Shae feistier than in the novels, a lot more willing to challenge and talk back to Tyrion, rather than just flatter and wheedle. I like her more as a character, but wonder if Tyrion is quite as likely to fall for this Shae as for the one who incessently flattered him in the novels.
I liked Grand Maester Pycelle's "the thing about kings" speech, and the prostitute's bored attitude toward it (and him). Was that Ros again, making an appearance? For the life of me, I can't figure out what the producers are attempting with that character. Is it cheeper to have only one actress on the payroll whose main qualification for her role is "looks good naked" rather than hiring several, or is this an actual attempt to tie a number of characters together through their "association" with Ros?
Oh well. A long wait till next season!
