Input: I had high expectations for this book and they have all been dashed! This is one of the worst books I've ever read. My review isn't based on whether you agree with or disagree with Rand's philosophy, but rather in her personal life. Not only was there no real emotional connection, she spent so much time attacking other people's beliefs even though she's probably got most of them right (except for Rand herself.
Output:
Bad review
