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.
Love everything by Adam Rubin, and heartily recommend all his books. This is more of a rating reflective of my three year old's interest in the book. He liked this book just fine, it's just not for him on the same level as the Those Darn Squirrels books or the Dragons Love Tacos ones - which are constant go-tos in the evening literary rotation.
