Input: Consider Input: Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.

Output: Good Review


Input: Consider Input: I ordered the product based on positive ratings - which was a big mistake. My husband worked with both types of products and never heard anything about this product. He tried it one day to give him relief after being in agony for several days and could not tolerate either one. Perhaps we received a bad batch? We will be returning them.

Output: Bad review


Input: Consider Input: This Kindle version has no diagrams, and therefore you simply cannot learn much from it, as there are too few examples. The text does not contain enough detail to solve any problems. In my opinion, don't purchase it. You will be disappointed.


Output: Bad review
