Across all of the apps that I use to consume content, I only know one app that does this well: Criterion. Here, look:
https://www.criterionchannel.com/browse
First thing to note. You can browse w/o having to create an account!
You know what else Criterion does? Rather, what it doesn't do? It doesn't cut off the end of movies at the credits to spam me with what it thinks I want to watch next. There's no "you may like this other thing" based on my watch history. Rather, content is grouped already based on attributes of the movies, not based on my watch history.
Criterion cares about movies and about me as a movie watcher, and it shows.
I will pay Criterion $99/year till the end of time.
The only thing I'd like them to improve is their streaming quality a bit. The video stream is okay, but none of the soundtracks are anything but stereo at best, even for movies they also sell as Blu-ray that have multi-channel DTS soundtracks.
