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 analyzes reviews to verify trustworthiness.
This is actually material excerpted from a larger book of his. I highly recommend it to anyone who is only wishing to do the type of things on the cover. This book actually helped me to decide to get his other books. He has an entertaining writing style and his information is solid, and helpful.
If you know you want to really get into it (making paper mache monsters) then you could skip this one and just get a bigger one by him. But this one is good, though short. (but it's also cheap. (which is good in it's way too))
