Overdone; trite (5)
I believe the answer is:
banal
I believe this is a double definition.
'overdone' is the first definition.
(I've seen this in another clue)
'trite' is the second definition.
(I've seen this in another clue)
(Other definitions for banal that I've seen before include "lacking interest?" , "Boring or trivial" , "Tediously unoriginal" , "Uninspiring" , "Tediously commonplace" .)
