input:  Now, answer this question: Title: Ugh Review: How does an author who cannot even write convincing dialog manage to win the Hugo? Don't ask me. The worst is the character Silenus, a crazy poet, who speaks like someone straight out of a B sci-fi movie. A couple of the stories are actually interesting but if you're into "hard" science fiction, don't even consider this book. Simmons is heavy on the speculative but low on scientific content. He should stick to writing horror. Is this product review negative?

input:  Now, answer this question: Title: A fine performance of an avant garde classic. Review: Cage's "Sonatas & Interludes" go back to when he was actually composing music instead of rolling dice. They're written for a piano which has its strings' vibrations modified by various pieces of hardware to make it into a compact percussion orchestra. Some pieces hark back to Webern, some look ahead to Glass, others sound like gamelan or a Cuban percussion section. In this recording Berman brings out the best in the music, nicely adjusting to its moods and eccentricities. At its bargain price this recording is a must for all interested in the milestones of American music. Is this product review negative?
