Human curation seems to be the only way out, but it can be so unergonomic. I don't really want to watch no-name movie reviewers on YouTube for hours until I find some I agree with. I don't want to read rambling blog posts to figure out whether or not someone liked a film.
The ideal flow for me would be: rate a handful of films, then it provides a list of curators that I can choose to follow. Each curator has a list of films that they've endorsed ("you should check this out, for this reason").
