input:  Now, answer this question: Title: A talking head doesn't equal a writing head. Review: Big disappointment. I saw Brokaw on the talk shows and had high hopes for The Greatest Generation. But the author's dry, uninspired writing style made reading more chore than pleasure. I soon found myself skimming. I can recall only a few of the chapters. As a more readable subsitute, I recommend the similar book by Studs Turkel called, I think, The Good War. It was told in the words of the subjects themselves. Is this product review negative?
A:
output: Yes

input:  Now, answer this question: Title: fragile changed my life. Review: as but a young pup when yes released fragile, music still had the ability to shape your reality, the very way you saw things. with the addition of rick wakeman on keyboards and roger dean on artwork, yes created something totally unique, their own universe. there are a lot of great artists out there today, but no one has ever made a statement like fragile (sgt. pepper maybe!) later the same year yes would release close to the edge. how is that even possible?fragile still has a ring of innocence to it missing in later recordings. it's almost as if they, too, are in awe of that which is being created. a stunning, beautiful, perfect album.
