Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

First of all, don't even bother mentioning Sixty Watt Shaman in the same sentence as Alice and Chains and Soundgarden. Cantrell has more talent in his pinky than Sixty Watt has all together. If you want to check out real Stoner Rock, Kyuss and Queens of The Stone Age are a good start. This album is mediocre at best. Red Colony seems to be the only song I could really get into. Cool album cover though! Maryland must have a really lame Stoner Rock scene, because out here in CA, Sixty Watt Shaman would go unnoticed.
Negative

This book has solved the problems we had while trying to manage my son's diabetes.You can find all answers in diabetes management.
Positive

My nutritionist (who is a celiac) asked me to burn this book! The advice is fanatical. Throw away your non-stick cookware, plastic containers and wooden spoons because they are contaminated. Pleassse!
Negative
