Example Input: i did not enjoy this book at all. it was pretty boring. the only part of my interest in reading and finishing is finishing what we started. unfortunately, it didn't come together for me.
Example Output: Bad review

Example 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.
Example Output: Good Review

Example Input: Bought it to replace our old comforter set. Nice quality and color. Just the right size for us. We love it!
Example Output:
Good Review
