input:  Now, answer this question: Title: Need serious editing!! Review: I picked up this book because it came highly recommended however I was pretty disappointed. There are continual awkward phrases and plot holes that could have been easily fixed with a good edit! I don't usually write reviews and I am often oblivious to prose that others might find objectionable but I just had to comment on this particular book because the issues were so glaringly apparent even to me! I found it almost unreadable. The story has potential but the whole book feels unfinished. Is this product review negative?

input:  Now, answer this question: Title: looks great but fundamental design flaw Review: The wine opener is a beautiful device. However, on first use, the cork got stuck in the screw and I was unable to remove it from the opener. Unfortunately, it has to go back. I'm sure this doesn't happen often, but if you buy this and you ever do get a cork stuck in the screw, then you'll be left with an unusable wine bottle opener. Also, it takes up valuable counter space because it comes in a stand. Be sure you have counter space that you can reserve for this opener. Otherwise, choose a different one that is small enough to go in a drawer. Is this product review negative?

input:  Now, answer this question: Title: Explains a problem few know about today. Review: I did not even realize navigation was a problem in the time of Isaac Newton, or that longitude could not be accurately calculated. This was a fascinating look done in typical NOVA style into the problem, and how it was solved not by the great mathematicians and astronomers of the time, but by a watch maker. A nice video for those interested in science, navigation, or history. Is this product review negative?
