And as you said, I'd much rather own the bluray for $19.99 then pay $5 for a sub-par rental. Heck, the dvds are $12 for the same title if not less. Besides, who wants the watered down 720 "HD" when 1080 is where HD truly is. 720 is just a marketing gimmick and should never have been allowed to have the "HD" phrase go with it.
If you're such a quality snob you should be insisting on 4K theaters as your only method of entertainment. * I love people who talk about insisting on the best and yet pick something right in the middle to proclaim as their version of 'perfect.'
So enjoy spending $100 on 5 movies for the month.
I'll be renting the $4 720p versions, realizing they look fine, and then going out and enjoying my extra $80 each month.
* (And the fact that many films are only released in 2K should give you an idea of just how important 'resolution' is. Hint: It's not nearly as important as inter- and intra-frame compression is. Movies are not video games or cell phones. The pixels matter a LOT less than you seem to think they do.)
