I enjoyed it, but at some points it was just too dark for me to see well, and the dragon stuff I had no idea what was going on. I was watching on HBO from the laptop. The final sequence with the music was fantastic, and the whole thing was indeed exhausting, in a good way.
The one thing I'd say is that it lacked some of the crazy, cruel surprises of GoT. Characters who died were very likeable but generally minor, and while the Arya thing was surprising in the moment (and crazy how easy it was, wtf; the old dead dude can beat a dragon with one had but Arya killed him with a cool custom-made knife), it was in some ways predictable she'd save the day.
I'd imagine some of the cruel surprises will come in the final chapters.
