Mubi's catalogue is tiny, and I find their marketing and interface (which strongly imply all the shows that have ever been been on the platform are currently on the platform, misleading). Criterion Channel (https://www.criterionchannel.com/) is a similar art film / critically acclaimed film network, which an enormously larger and more diverse catalogue. Officially it's only available in the US but if you sign up through a VPN it works everywhere.
