Why is something considered overrated?

Answer 1

An object can be rated on how well it meets given criteria. For example, food can be rated on how well it tastes, or how nutritious it is. But an object's rating does not necessarily equal how well it meets the given criteria; it is a subjective measurement representing how well the rater thinks it meets the criteria. For instance, a rater with a poor understanding of nutrition may rate a food to be more nutritious than it is. In this case, when an object's rating exceeds its actual value, it is considered overrated.
