I think the main problem is that a single value score means different things to different people. Most people think it means “entertaining”, film nerds think “original”, cineasts think, well, I don’t know actually, but I’d imagine a sum of technical aspects.
One solution would be to split up the rating into aspects, another to filter ratings according to similarity in preferences. None of these are perfect though and the latter may even be another social media trap with all kinds of inherent problematics.
My workaround is to have a quick glance at the different review boards I know for their audience and weigh the scores to the type of movie if it’s worth a two hour investment of time or not.
Personally I came to the conclusion a long time ago that there is no reason for me to rate movies for how faux objectively “good” they are. I don’t rate movies for anybody else. I rate them to keep track of what I’ve seen from people in the production. I try to give it some context, but ultimately it’s an entirely subjective rating for myself.
