One Opinion

We are movie buffs.  And we've determined that some movie critics have none of the same criteria that we have in determining the likability of a movie.  Movie critics actually only represent one opinion.  When we're relying on another's opinion, we need to ascertain that they view things as we do.

When it's a movie, the stakes are low. However, if it's a surgeon, employer or university, the stakes are high.  We need to know that their assessment matches ours.
