Task: Sentiment Analysis
Input (English): I don't understand why all the 5 star reviews for this book. The characters were underdeveloped and most of them seemed to have no character at all. For example, the supposed hero, a half angel, kept referring to an angel in his own blood as &#34;that old boy down there...&#34; He would seem to know nothing about angels, let alone their mission in life.
Output (English): Bad review
