Not perhaps digging someone's grave (8)
I believe the answer is:
critical
I believe this clue is a double definition.
'not perhaps digging someone's' is the first definition.
(dig can mean to like something)
'grave' is the second definition.
(similar in meaning)
(Other definitions for critical that I've seen before include "giving literary analysis" , "Adversely commenting" , "Expressing disapproval" , "Crucial, decisive" , "All-important - disparaging" .)
