Most rating systems suck because the rating is relative to the reviewer but the interpretation is relative to the reader. And of course the rating relative to the reviewer at that time.

After decades of reading, there are probably only four fiction ratings for me:

Recommend - to a specific reader or genre

I read it multiple times over years

It's OK, but at this point it's bookshelf filler

I sold it.

There's usually a good thing in every book. I mean, the first 8 Stephanie plum books were fun...but it gets old. The hobbit/LOTR? I'd never recommend those today. I loved thr Thomas Covenant stuff back in the day, but today? No. But The Black Company and Garret PI series are the gifts that keep on giving.

Capturing that in a one dimensional measure is impossible...but it's been Good Enough for years. But you can try to make it better.
