To calculate the overall star rating and percentage breakdown by star, we do not 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 son loves this series and tells me all about dog man (I thought it was a joke at first). I would recommend this as it has given him (8) and his sister (9) lots of laughs about the bad tadpoles, but there is one good one, and the granny fairy.
