Sweet counter in Picturehouse cinema (4)
I believe the answer is:
nice
'sweet' is the definition.
(I've seen this in another clue)
'counter in picturehouse cinema' is the wordplay.
'counter' is a reversal indicator (counter can mean in the opposite direction).
'in' indicates the answer is hidden within the clue.
'ecin' is hidden within 'picturehouse cinema'.
'ecin' reversed gives 'NICE'.
(Other definitions for nice that I've seen before include "Agreeable -- subtle" , "French resort; agreeable" , "Place in France that sounds agreeable?" , "French resort; pleasing" , "place near Cagnes-sur-Mer" .)
