This is weird, but I’m sure it will get a full Blu-ray release pretty soon. It’s a divisive movie, and frankly I really struggled to get through it (the dialogue was so contrived and stilted). I found myself frustrated and yelling at the screen more than once, but I’d likely grab a 4K Blu-ray whenever it comes out so I can give it another chance and see if I somehow totally missed the point.
I think the movie is probably good from a technical perspective, and the message it tried to communicate was worthy of the attempt, but the plot was incoherent, the dialogue was impenetrable, and the gorgeous visuals were completely out of step with the overall narrative.
:( I was actually thinking about buying it. This isn’t even a joke
Makes sense. Currently listed as “Unavailable” and the home video discs have no listed release date:
