Slasher film feature (4)
I believe the answer is:
gore
'slasher film feature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gore that I've seen before include "Coagulated blood from a wound" , "Pierce with horn - blood" , "Blood; stab with tusk" , "Result of bleeding" , "Blood that's been shed" .)
