Scathing review (3)
I believe the answer is:
pan
'scathing review' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pan that I've seen before include "Greek nature god" , "hammer" , "Woodland god with merry merry pipes" , "In Greek myth, the god of flocks and herds" , "A vessel; chimp genus" .)
