Example Input: Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
Example Output: Positive

Example Input: At first I was disappointed that this wasn't a longer book, but then I realized that it is great to give away to curious friends and parents as an introduction to Love and Logic. I just wish it was a little cheaper.
Example Output: Positive

Example Input: Ok, the kids accused me of reading it because its full of boats, dories, fishing boats, rowboats, skiffs, mailboats etc and they are right. But I liked it most because it showed the kids thinking and the dangers of not trusting your brain when you are in trouble and the way out is not by getting into more trouble.The kids, before committing to read it, also wanted to know that no dogs die, and no one dies in the story. They are sick of stories where the main character or their dog dies. So there are dead people mentioned in the book, a dead mother, but she's long gone by the time the story starts.Anyway I liked it. The depiction of being out in the storm was very true to life, as was the actions of the kids.
Example Output:
Positive
