The binary of fresh/not fresh has always been problematic too. It takes away nuance and rewards palatable mass market movies that most people like but that aren't polarizing enough to be interesting.

This is why I don't go to aggregate sites like this for reviews. I only ever listen to opinions from youtubers I've found online who have similar likes and dislikes as myself. Now I've got a tight cluster of people who can help me get a good gage on if I'll like something or not. It isn't perfect, but it works.

If you’re just looking for a number that tells you if the movie is worth watching, I bet Letterboxd is a good source. I don’t write reviews, but I’ll add a rating for every movie I watch. Partly because that’s the easiest way to tract my movies. I bet many do that.

There is still the audience score and the top critics score. This will need to be looked at specifically but shouldn't have the same issues as the overall ranking. If that section is useless except for marketing just ignore it
