Task: Sentiment Analysis
Input (English): I've been collecting and displaying model rockets for at least 25 years. Most are from the 60's to 70's, many of them well over $100 each. Even after all that time I found this book disappointing. There is more about how rocket parts were developed than anything else. Very thin coverage on the history or manufacture of any particular rocket. One would be much better off finding another guide book. There's really nothing &#34;new.
Output (English): Bad review
