Calling attention to errors and flaws (8)
I believe the answer is:
critical
'calling attention to errors and flaws' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for critical that I've seen before include "At crucial stage, or being disparaging" , "Extremely important" , "essential" , "Looking for faults, or at important point" , "Extremely ill, near death" .)
