I watched it through my pc and tuned the brightness and contrast so it was less dark but dark enough
I watched the first half on my phone while on a train in daylight so I mostly just heard things
Then finished off on my laptop with a poor TN screen. Definitely made a difference rewatching it on the TV with the lights off!
Bits I didn't like definitely don't get any better, such as very questionable battle tactics from the living. Few annoying Hollywood cop outs and biggest one is the whole NK thing, if this is how the whole White Walker story arc ends, it is very cheap and disappointing. Let's hope Bran's role is a bit more than just rolling eyes back and being cryptic. Still half a season to go and things can change quickly in this show.
Maybe whole White Walker thing is just a way to reset humanity and wicked ways of man so to speak. So now that NK is no more, Bran will continue on that legacy in some way at the end.
Also they had a few dozen guards around Bran but didn't spare anyone at all for the crypt?
As far as deaths go, I was probably most sad about Jorah and Beric. Theon suffered same fate as the Dothraki, pointlessly killed for cinematic effect.
