Picturegoer gutted about some current spoiler? (8)
I believe the answer is:
pamperer
'spoiler?' is the definition.
(I know that coddler can be written as pamperer)
'picturegoer gutted about some current' is the wordplay.
'gutted' suggests removing the centre (to gut something is to remove its insides).
'about' is an insertion indicator.
'some current' becomes 'ampere' (amperes measure electrical current).
'picturegoer' with its middle removed is 'pr'.
'pr' going around 'ampere' is 'PAMPERER'.
(Other definitions for pamperer that I've seen before include "indulgent type" , "Mollycoddler" , "One spoils by excessive indulgence" .)
