Overrated is a word people use to make themselves sound more credible. If you use it, it implies extensive experience and qualifications to make a judgement.

If we were sitting around and chatting without really knowing each other (which we do) saying it (the subject) is overrated is an easy way to say you don't like something, because it implies that you have experienced a diverse collection of the subject and are qualified to make that statement.

Or something.;)
