Stupid shiny wrappers poorly received (5)
I believe the answer is:
silly
'stupid' is the definition.
(I know that stupid can be written as silly)
'shiny wrappers poorly received' is the wordplay.
'wrappers' suggests removing the centre.
'poorly' becomes 'ill' (similar in meaning).
'received' is an insertion indicator.
'shiny' with its middle removed is 'sy'.
'sy' placed around 'ill' is 'SILLY'.
(Other definitions for silly that I've seen before include "Inane; very close (fielder)" , "Trivial, frivolous" , "Ridiculous, frivolous" , "Stupid" , "Ludicrous, foolish" .)
