Example Input: This book was the worst one I have ever read. It should be required reading for anybody in politics. Do not support this trash book. He calls people who don't agree with him liars and racists. That's just gross. If we really care about other people, why are there lies that would take away from people's rights. He's the definition of a politician. The only person he has is himself to blame if he's so stupid to believe these stories. He seems like an intelligent, kind man.
Example Output: Bad review
