Reporter's evaluation for show (5)
I believe the answer is:
revue
'for show' is the definition.
(revue is a kind of show)
'reporter's evaluation' is the wordplay.
'reporter's' indicates a 'sounds like' (homophone) clue (report can mean to speak something aloud).
'evaluation' becomes 'review' (I have seen 'Critical evaluation ' mean 'review' so perhaps 'evaluation' could also mean 'review').
'review' is a homophone of 'REVUE'.
(Other definitions for revue that I've seen before include "Kind of show with sketches and songs" , "Entertainment consisting of sketches" , "Song and dance entertainment" , "Musical show" , "Stage entertainment with sketches, songs and dance" .)
