it's kubrick. it's a masterpiece.
i don't really like movies about couples but being kubrick, i gave it a chance. the cinematography is just so incredibly rich, not only with flashy scenes and beautiful colors and framing, but with all these referential easter eggs and nuggets of hints and symbolism and...oh my god it's just RICH. if you like psychological and mystery stuff, and photography, and lurid secret society stuff, this movie is incredible. i will watch it again for sure.

4k blu ray scenes freeze
The movie is good. The 4k blu ray froze at one scene and skipped ahead a few scenes. It makes me sad. Hopefully the blu ray doesn't freeze.

The 4K's Rating
I'm not sure what's going on with this release, as it gets praised by some, condemned by others. Very strange. For me, all the criticism of the colors in some scenes (like the teal & orange bedroom scene) makes no sense, because those colors do not appear as saturated and forceful on my Panasonic 4K player and Samsung 42" 4K TV. They look noticable, as teal and orange naturally clash at any strength. But they don't look entirely unnatural. As for the grain, it iS awful during the initial party scene, to the point of distraction. But as the movie progresses, it seems to weaken. I'm not sure at what exact point the distraction ends, only that I became fully absorbed in the movie before Bill's nocturnal "adventures." (As a matter of note, I don't oversharpen in the settings, and don't bump up saturation.) This rating is for the 4K. I've only watched about 20 minutes of the blu-ray, during which I encountered a 3-4 second sound dropout that was troublesome. As in SILENCE. It's something I intend to contact Criterion about, to see if this is an anomaly (in which case I'll initiated a replacement from Amazon). If it's a general problem, I'll ask Criterion for a blu-ray replacement. I want to watch more of the blu-ray before taking any action, in case there are more dropouts to report. BTW, the blu-ray looks quite good to me, altho I think the 4K is slightly more detailed.
