Input: Consider Input: This book was written in the 70's by a man who knows his stuff, which is a rare find nowadays. The problem with it is that he relies too much on anecdotal stories and anecdotical sources to support his hypothesis. It feels like reading someone's blog, not science. Also, some of the anecdotes don't make any sense unless you can explain away how they happened.

Output: Good Review

Input: Consider Input: The product works, but at no level is it particularly good to have or extremely bad as many other reviewers seem to be saying. It does look great, and feels nice, the material seems very sturdy, and even with a full charge, has sufficient battery life to last for hours of usage. BUT.

Output: Bad review

Input: Consider Input: My daughter loves it. I was pleasantly suprised because this is a small doll, and very pretty. She takes her everywhere's with her.
Output: Good Review
