Reviewer is getting English roast (9)
I believe the answer is:
criticise
'roast' is the definition.
('roast'->'criticize' is in my internal thesaurus and 'ize'->'ise')
'reviewer is getting english' is the wordplay.
'reviewer' becomes 'critic' (I've seen this before).
'getting' says to put letters next to each other.
'english' becomes 'E' (abbreviation).
'critic'+'is'+'e'='CRITICISE'
(Other definitions for criticise that I've seen before include "Point out problems or mistakes" , "knock" , "Find fault" .)
