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.
One of my son’s favorite bedtime books. Good to read aloud. Not very long and lots of guessing and inference needed to understand the story. Best if read together the first couple times until the child understands all the unspoken underlying jokes.
