input:  Now, answer this question: Title: a great film Review: I bought this film, cause my grandma at 81 years old had seen it in her youth. I got it for her as a gift. She cried when I sat down with her and watched it. I loved it. It' s a romantic film about what can happen in wartime. Great actors and a brilliant plot. I recommend this film.

input:  Now, answer this question: Title: Really bad in all ways Review: Horrible sound. Instructor doesn't give instructions and, worst to my mind, has no feel for the music, no sense of rhythm. She hurls her body around, and her movements are jerky, not fluid as most dance requires. Plus, she does certain movements that are notoriously bad to do, such as backward neck rolls and abrupt squats mid-motion. And she calls it "aerobic," which it isn't likely to be for anyone. Should be pulled from the market for both aesthetic and safety reasons! Is this product review negative?

input:  Now, answer this question: Title: Light...Too Light Review: Bears hints of the Mayle style, but fails to deliver - in character development, plot, and charm. A light, fun read, but pales in comparison to Mayle's other books. Sorry, but any reviewer who rated this book highly either is not familiar with other Mayle options, or took the book far too seriously. Is this product review negative?
