Fat Kid Rules the World . When I picked this book up, I expected it to be interesting. As a fat kid, I thought I would enjoy the story, thinking that I would feel connected to the main character. Boy, was I wrong. In the beginning of the book, Troy, feeling suicidal, wants to throw himself on the tracks, but Curt, a skinny druggie, stops him. By the middle of the book, I wish Curt had just held back and let Troy jump. The book was very slow for me; each new chapter sounded like the last. I read this short book over two weeks because I just couldn't take it. The end was unsurprisingly predictable. I mean, I could've told you what was going to happen by the fifth chapter. Usually, when I read a book, I take something from it, maybe a lesson or a moral. In this book, I just felt a sense of nonclosure... the ending didn't really do it for me. Based on the other reviews on this page, you probably think that I'm just a mean person who writes scathing reviews on great books. The first part may be true, but I only write scathing reviews on things I did not particularly like. You may not have liked Macbeth, but I sure did. Whether it's a good book or not is all a matter of opinion
Output:
NEG
