Task: Sentiment Analysis
Input (English): I got this book as a gift and was very excited to open up the package. Unfortunately, it's a total disappointment. The author obviously did not do any research on her topic of time travel (which seems so simple in theory and makes it sound like science). She used some words that made no sense, such as:&#34;In fact, my mind is working at warp speed because I'm doing some intense thinking right now.
Output (English): Bad review
