If you aren’t aware, there’s a huge amount of Criterion titles on HBO Max.
I did notice some, such as Seven Samurai. Problem is that HBO Max doesn’t seem to feature a Criterion hub in the same way they have for other channels, like Adult Swim for example, so I have no way of knowing the full extent of their Criterion selection from within HBO Max, unless there’s something I’m overlooking, that is.
Classic films are under the Turner Classic Movies hub, which is where all the Criterion titles are.
