I'm a subscriber, but the Criterion apps do downloads right some of the time if you're lucky, the choice of subtitles is usually English or English, discovery is Netflix-level bad, they can't be bothered to create any interactive info, and most of the actual Collection is not available for streaming.

I still pay them every month because they have the goods but it's so frustrating that the people with the most film-buff oriented catalog and their hearts (presumably) in the right place have so little ability to deliver on UX.

(I used to subscribe to MUBI as well, which is stronger for new indie films, but didn't have time for both, and MUBI app was so bad it could have been a fork of the Criterion app.)
