Thanks for the review David, I've been wanting to see this. It's disappointing that as far as I can tell, there is no 4K version available. HBOMax doesn't seem to support 4K, which seems like a huge miss in this day.
News today that new WarnerMedia CEO Jason Kilar has announced a re-org which includes elevating HBO Max as its own operating unit with a higher priority. He was CEO of Hulu several years ago so he's obviously got roots in streaming, and the HBO Max head is another guy with Hulu experience, Andy Forssell. I would think it reasonable to expect HBO Max to quickly start ramping up its capability and offerings.
Except that 4K and HDR have never been a priority at Hulu, so will it be any different with these ex-Hulu executives at HBO Max?
