It often is based in reality, but my experience with talking to people that most of them never really consciously think about what aspects of this reality irks them. Any attempt to get people to think a bit will just anger them.

A reminder to everyone that "I don't know" is a valid answer, and that your feelings are valid. If you feel a certain way about a piece of work, then that's how you feel. You don't need to make shit up to explain it. If you do want to explain it, then actually take the time to think about it before you do.
