Enthusiastic review (4)
I believe the answer is:
rave
'enthusiastic 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 "Rant about an all-night dance party?" , "Rant - noisy, all-night party" , "Lively party" , "Talk with extreme enthusiasm or wild delirium" , "Talk wildly in modern youth dance" .)
