Trite or banal (5)
I believe the answer is:
corny
I believe this clue is a double definition.
'trite' is the first definition.
(I've seen this before)
'banal' is the second definition.

(Other definitions for corny that I've seen before include "Over-sentimental; trite" , "Banal and not amusing" , "Not original" , "Platitudinous" , "Hackneyed" .)
