Good review (4)
I believe the answer is:
rave
'good review' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rave that I've seen before include "Talk wildly in modern youth dance" , "Laudatory sort of review - quite a rant" , "Rant - noisy, all-night party" , "Rage" , "Wild party; go mad" .)
