Well, I'm not disagreeing.
I started streaming it yesterday, and did so at various locations and TVs. The bigger [and more HDR] the TV, the better, moreso than with other films. I really get the sense that this was designed as a 'cinematic' experience more than the average film.
That doesn't mean it will translate into an awesome Imax film, just that it was designed for that experience rather than home-streaming.
I also don't understand why the royal families prefer such austere surroundings, maybe it supposed to be part of their martial culture. Villeneuve paints a bleak canvas, that's for sure.
Sound design was shot. And there's a lot of people elsewhere saying the same.
