The Amazon rating system is subjective. What may appeal to one person and rate five stars, could end up with a three-star or lower rating by another reader. So much depends on taste, likes, reading level, and the reader’s relationship with the author.
Here are my simple and personal criteria for rating books on Amazon.
I couldn’t put the book down and when I did, I couldn’t wait to pick it back up again. Didn’t want it to end. I highly recommend this book.
I liked the book. It read well and was interesting. I would recommend this book.
The book was okay but lacked the ability to connect with me. May have some typos and editing errors. Not likely I would recommend this book.
This book was poorly written and not engaging. I had to work to get through it. I may have skipped through some parts. I would not recommend this book
The writing or content was so bad I couldn’t finish this book.
