Everyone says the Goodreads rating system is terrible yet many people still use it when choosing a book to read next. What books under four stars are the best example of great books that the general population doesn’t seem to recognize as such?

I know booktok has resulted in a ton of low quality books having absurdly high ratings on Goodreads which also similarly demonstrates the unreliability of the rating system. Storygraph is regularly recommended as an alternative though it suffers by not being as widely used so often less known books have very few ratings or reviews. The ability to utilize quarter points though allows for a lot more accuracy as often a book doesn't fall exactly at three or four stars.

I think it's been well demonstrates that Goodreads choice awards do not always reflect well on the actual quality of the literature and many books end up on the lists that are far from remarkable or what you would expect from an award winning book. What underrated books are suffering from the unreliability of making choices based on what is successful in the mass media?
