Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
This is a fun book! Some of the jokes are unclear for Americans, as the author appears to be British. Nevertheless, 95% American kid gold. Be aware, these jokes will be told by your 5-year-old ad nauseum, so thank goodness it’s cute.
My daughter really liked this book. Got for her for Christmas last year. We enjoyed going through the jokes for a 5yr old. She only understood about half of the book... but enjoyed me reading it to her all the time.
