I think that numeric ratings (especially if only one number can be specified) (and then averaging or making or other types of statistics) are not as useful as actually reading the reviews in order to determine whether or not it addresses your concerns with it, and if they have specific complaints or specific things they say are good, to judge them by yourself according to your own intentions.
Agreed. And particularly with the advent of LLMs, this is something that could be done quite easily. Don't even give users an option of giving a numeric/star rating - just allow people to write a sentence or two (or 10) and let the LLM do the sentiment analysis and aggregate a score.
