input:  Now, answer this question: Title: What a POC product. Review: This product has nothing good about it at least for me. Did not help with weight loss, appetite control or anything worth while. The negative side effects are even if I take it 5 hours or more before bed time I am still awake two or more hours after my bed time. This product is worthless. What a waste of money. The only way I will lose weight is good old fashioned hard workouts that include aerobic, anerobic and weight training alongwith calorie control. Eat to live not live to eat.Total disappointment!!!

input:  Now, answer this question: Title: totally unbelievable story Review: Based on the glowing reviews, I thought this book would be extremely sexy and romantic. Instead, it was just jaw-droppingly stupid. No man or woman, even today, would have sex in an exhibition hall unless they were an exhibitionist and wanted to be caught at it. With all the risks involved, that's not sexy, it's just dumb. The sex scenes between them were beyond cartoonish. I can hardly imagine a man today (except in a porn movie, maybe) using such silly words (such as the repetitive use of both the female and male C words) with a stranger, let alone over 150 years ago. The author totally wore those words and the F word out. And the scene where Mark argues with his mother and the size of his and his father's genitalia are mentioned, was offensive. I think this book deserves 0 stars. Is this product review negative?

input:  Now, answer this question: Title: Exceedingly Difficult But Rewarding Puzzle Review: This puzzle let me to the breaking point on more than one occasion. The hanging curtains were very difficult to put together. Also, the picture frames seem unique but the sheer volume of puzzle pieces that made up the frames made them pretty hard also. The other tricky part is that the vast majority of the puzzle involved muted tones. However, you get a beautiful finished product at the end. Is this product review negative?
