'Coward' means somebody who easily gets scared. Unless you are saying that watching a lot of horror movies actually makes you more of a scaredy-cat, I think the word you are looking for is 'scared'.

cowardliness means not coward

It is the first time I heard that horrible movie can make a coward . In my opinion, the real courage is supposed to be responsible for what they did and the the coward is timid to admit what they did. I know some girls who love watching horrible movie , however, they are quite timid in reality.

 

ok, thank you :)

Horror movie

Watching an horror movie can make someone cowardly.
