I once helped develop a "survey" for a nonprofit org, which wanted to gain some insight on what they were doing well and what they could improve. One of the other people involved kept insisting on reducing the number of questions and complexity of the ratings. He said it all boiled down to one basic question, "would you use this service again" and while we didn't quite get that simple, in retrospect I think he was more right than wrong. Maybe a boolean "would you buy this product again" is the basic question for a review. It's still open to being gamed, but only in one way.
