Rather crude show about torture avoiding extremes (10)
I believe the answer is:
indelicate
'rather crude' is the definition.
(indelicate can mean crude or coarse)
'show about torture avoiding extremes' is the wordplay.
'show' becomes 'indicate' (synonyms).
'about' indicates putting letters inside.
'torture' becomes 'hell'.
'avoiding extremes' indicates the central letters (letters at the extremes of the word are removed).
The middle of 'hell' is 'el'.
'indicate' placed around 'el' is 'INDELICATE'.
(Other definitions for indelicate that I've seen before include "Saucy" , "Rather rude" , "Rude - tasteless" , "lacking taste" , "Practised (a play)" .)
