uses and gratification theory
the theory is that you would use the media to gratify how you feel and what kind of mood you are in
for example
if i was happy i would watch my favourite film that i would know wouldnt put me in a bad mood
personally i would watch: arthur (modern version) becuase although it has sad parts in it, it still has a good ending and makes you smile after you watch also aall the little jokes put in makes you laugh and is a pleasure
if i was sad then i would watch a sad film for example; my girl becuase it still is intresting but is also very sad so would match the mood you were in and if the characters were in a similar situation you were at the time then you would be able to realte to the characters and understand more what the writers and directors intentions were in the film.
if i was bored then i would watch a romcom like: when harry met sally or chocolat becuase these are the genre type of films that i enjoy watching the most and this kind of contredicts the theory becuase if i was in a bored mood then i wouldnt watch a boring film becuase i would want something that would interest me and what i would want to watch.
