I had lights off and my tv on full brightness and still had trouble making shit out. I still have no idea why the hell the Dothraki decided to randomly charge when we couldn't even see the bad guys. And I thought Jon had just lost his mind yelling at the ice dragon until I found out he was yelling at Arya and distracting the zombiedragon.
It's good and I love it but tbh, I have no idea what's happening half of the time.
