Just finished my 2nd watch.
From a battle perspective and visuals it was amazing (not tactically).
Plot armour however, is annoying and I expected more main character deaths. I did like how Jorah and Theon went out though (oh shit and Beric, was a surprise to find out why he'd been brought back and how he also resembled a cross at one point). Sam should have died about 10 times, but he probably has the most plot armour, they should have just put him hiding in the crypts.
Crypts was also disappointing, best part was when Missandei said you'd all be dead without the Dragon Queen. Again annoying plot armour when the dead were risen down there.
I don't mind Arya killing the NK, it was surprising. If she also gets the kill on Cersei I'll probably be slightly pissed (brown eyes, green eyes...).
Still happy with it and I'd give it a 9/10, but I can understand the complaints made. I was still thoroughly entertained.
