Problem arising with contrived sequel - it's supposed to be entertaining (9)
I believe the answer is:
burlesque
'supposed to be entertaining' is the definition.
I can't judge whether this definition defines the answer.
'problem arising with contrived sequel' is the wordplay.
'problem' becomes 'rub' (the rub can mean a problem or catch).
'arising' says the letters should be written backwards.
'with' means one lot of letters go next to another.
'contrived' indicates anagramming the letters.
'rub' backwards is 'bur'.
'sequel' is an anagram of 'lesque'.
'bur'+'lesque'='BURLESQUE'
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for burlesque that I've seen before include "Entertainment based on broad and earthy humour" , "Mocking, perhaps" , "Ludicrous satire" , "Takeoff" , "Ludicrous imitation" .)
