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.
For someone that's just likes to read aimless story's well this will do. It's like watching discovery channel and at the end you don't know any more then you did to begin with - It's just entertaining !
