A solid 7. I actually liked it, many things to enjoy.
My higlights were Arya's scenes, it was great to see a girl who had suffered and lost so much, to the point that the only thing she had left was hate, and so damaged that the only thing she could see in her future was revenge... suddenly realizes that she hadn't lost everything after all, that she still has a family (a s smaller one perhaps, but still a family) and a home.
As for the rest, I enjoyed almost everything, leaving aside some unpleasent details, as the disgusting scene of the "surgery" practiced by Sam on the poor Jorah
I even liked Missandei/Grey Worm scene, I found it touching. But IMO with only 5 ep left in this season, this time screen might have been better used.
So my complaints are not as much about what the episode had, but rather about what the episode lacked.
