The beginning of Evil Dead bringing cheer (5)
I believe the answer is:
elate
'cheer' is the definition.
(to elate is to cheer or make happy)
'the beginning of evil dead' is the wordplay.
'the beginning of' indicates taking the first letters.
'dead' becomes 'late' (similar in meaning).
The initial letter of 'evil' is 'e'.
'e'+'late'='ELATE'
'bringing' is the link.
(Other definitions for elate that I've seen before include "Fill with optimism" , "Delight" , "Bring joy" , "Fill with joy" , "Fill with high spirits" .)
