The natural inclination of any consumer search through Yelp is not to find the 5-star review, but to find out why somebody did not receive a five star review.

The problem with a blemish review is simply the doubt that it plants in the consumer mind, particularly one who is comparison shopping. That nagging feeling of second guessing happens to anybody who reads one poor review for a camera or a car, and it forces them to delve deeper into qualifying their choice.  On the other hand, perfection passes with flying colors and has become the standard on review sites. It's a hard reality.
