The Leveller and Good Soldier both have points: performers should take rough with smooth, and reviewers should have and observe guiding principles. i have mine I cannot pretend to speak for others and nor would I wish to.

FloraG; the response to the original question suggests reviewers do have a place. No one needs to be unduly influenced by what they have to say. They may do no more than produce a good or not so good piece of writing. They may alert you to something you find interesting. But anyone who takes their conclusions too seriously, without testing the water for themselves (unless the reviewer is someone they have come to trust), is somewhat gullible.
