Appear so excited about nothing in TV drama (4,5)
I believe the answer is:
soap opera
'tv drama' is the definition.
(I've seen this before)
'appear so excited about nothing' is the wordplay.
'excited' indicates anagramming the letters.
'about' is an insertion indicator.
'nothing' becomes 'O' (looks like zero - 0).
'appear'+'so'='appearso'
'appearso' is an anagram of 'soappera'.
'soappera' placed around 'o' is 'SOAP-OPERA'.
'in' acts as a link.
(Other definitions for soap opera that I've seen before include "Melodramatic TV serial" , "Long-running story supposedly true to life" , "TV or radio series of everyday events" , "Everyday drama serial" , "Fair City or Coronation Street, say" .)
