input:  Now, answer this question: Title: tripe is actually very good, it provides the soup with body Review: The tripe is minced very small and cooked for 3 hours so that the cartilage in it breaks down and gives the soup thickening and body without adding starch or flour to cloud it up and mask the flavors, ditalini pasta masks the look of the bits of tripe which might look odd by themselves; add bay leaf and marjoram if not listed on the label if you want the Philadelphia Pepperpot authentic, oxtail was sometimes also added as meaty and fatty content, savory and basil and leaks and dumplings are optional; butter and vinegar as condiments.

input:  Now, answer this question: Title: One of the great mysteries of literature... Review: ...namely, why the hell does anyone buy this guy's books, let alone enough of them to propel them to best-seller status?Crude prose, mechanical plotting, ludicrous motivations, cheap suspense tricks, shoddy scholarship and geography, cardboard characters: lord, the list goes on.Seriously, save your money. Maybe its follow-up, ''The Da Vinci Code", takes an enormous leap in quality, but I'm not willing to test that theory without some firm evidence. Is this product review negative?
