Frenzied, smashing cinema - no point (5)
I believe the answer is:
manic
'frenzied' is the definition.
(I know that frenzied can be written as manic)
'smashing cinema no point' is the wordplay.
'smashing' indicates anagramming the letters.
'no' is a deletion indicator.
'point' becomes 'E' (compass point).
'cinema' with 'e' taken away is 'cinma'.
'cinma' anagrammed gives 'MANIC'.
(Other definitions for manic that I've seen before include "Pathologically excited" , "Obsessive" , "On a pathological high" , "Wildly energetic" , "Berserk" .)
