Streaming such a high fidelity movie seems like a waste. Seeing the difference between a UHD 4K Blu-ray and a stream of the “same quality” it’s almost night and day.
I do have most Nolan films in 4K Bluray but Tenet isn't available yet. Before buying the physical media I'd be more than happy to see it via streaming with acceptable quality.
On the other hand, if the cost of streaming it as a rental is as high as the physical media copy...
Totally. But as a Nolan fanboy I really want to see Tenet and wouldn't mind paying extra to see it before the physical release.
