Critics rebuke discontented audience members (9)
I believe the answer is:
reviewers
'critics' is the definition.
(I know this)
'rebuke discontented audience members' is the wordplay.
I cannot quite understand how this works, but
'audience' could be 'viewers' (viewers is a kind of audience) and 'viewers' is found within the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for reviewers that I've seen is " critics".)
