Off-topic, but I do the same with student evaluations (I teach at a research university). This seems to be human nature: good reviews tend to be fairly generic ("nice", "clear", etc) but bad reviews are usually very specific. On the flip side, when I write reviews, be it a product review on Amazon or in a referee report, I always try to include specifics in positive reviews.
