input:  Now, answer this question: Title: A must have for latin-jazz fans. Review: From surrealist psychedelia to smooth R&B to balls to the wall free jazz explosions, Carlos and company take you on a musical journey you'll never forget. The serenity of opening tracks "Eternal Caravan of Reincarnation" and "Waves Within" gradually progress, as the album plays, into the sheer jazz chaos of closing tracks "La Fuente Del Ritmo" and "Every Step Of The Way." This album, though maybe not for the casual pop rock listener, is a definite must have for any fan of Santana or of jazz in general Is this product review negative?

input:  Now, answer this question: Title: Needs a Crystal Ball Review: Clint Eastwood has to his credit a long list of great accomplishments. This film, which he produced and directed, is not one of them. Oh, it has its moments. The opening depiction of a tsunami striking a populous shore and a few other touching scenes scattered throughout the film do little to balance what is a confusing jumble of disparate story lines. An egocentric French journalist, twin boys trying to care for a substance-abusing mother, and a young woman haunted by her abusive father stumble along toward a nonsensical conclusion.Matt Damon plays a genuine medium (oxymoron?) who is trying to break away from a lucrative career as a psychic consultant because of the pain it all causes. Damon is not convincing. Perhaps he should have worn some exotic headdress. A long beard that glows in the dark? A high-tech crystal ball?I predict.....a big disappointment that will take up about two hours of your future if you watch this film. Is this product review negative?

input:  Now, answer this question: Title: Great read! Solid adventure! Review: Not often that the defeated soldier/sailor documents a war experience, so it is interesting to learn about the war from the German perspective. Werner is clearly not a literary genious, these pages read more like his diary, and one suspects the tales have grown a bit over between the fighting days and 1969 when the book was published. Some of it is clearly self-aggrandizing. But a very fine summer read for me, and if you enjoy action-adventure this will be a great book for you. (I read "Iron Curtains" immediately after finishing Krakauer's "Into Thin Air" about the Everest adventure, and the similarities of adventure-tragedy are apparent between the two books.)
