Similar to the other commentor who ignores stars and only reads reviews, I do something similar, but I mostly only read negative reviews.
The problem I have is that positive reviews too often just uncritically praise the book, telling me nothing about why the book is good or why it might be bad. (And the fact that bots are so prevalent only makes this phenomenon worse).
On the other hand, negative reviews often directly state what the reader disliked about the book. So, I hunt through negative reviews to find reviews that hint, or directly mention having elements of the book that I like/am in the mood for.
For example, one time I was in the mood for fantasy where the protaganist does magical research. So I found this one book and started looking through reviews, and I saw this 2/5 star review where the reviewer was complaining "MC never fights, they just research and grind in the lab all day". I started reading that book immediately, and I had a great time.
