To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
My grandson, age 9 and I are huge fans of this series. We have read every one. We love the humor and have grown to love all the characters. Seen through the eyes of a child, A.J.'s world is priceless. I especially like this recent addition to the series as it deals with the up-to-date subject of Artificial Intelligence and it led into a broader discussion of the subject. We watched some video clips and read some scientific articles on some of the possibilities of AI (positive and negative.) Well Done, Dan Gutman
