I think karma plays an important role in any script and it will attract more viewers/audience. As an example of karma in a lot of stories the good guy that beats the villan and gets the girl and the bad guys who learn their lessons one way or another in the end.
Even by looking at some of the more deeper screenplays we can find the traces of karma. I think it's mainly because the audience would like to see some extent of justice or otherwise they would be annoyed and in the movies the only justice is some sort of karma.
As I searched online I couldn't find anything to support or reject this idea, so I'm not sure about couple of things:
- Is the concept of karma in movies (or any story in general) a valid idea?
- If yes, is it intentional or is it inherently in the nature of stories?
- What are some of the good examples that don't utilize this concept and how successful are those movies?
By karma I don't necessarily mean a good ending. I mean the act of receiving the consequences based on your decision, these consequences may very well be horrible and not happy.
P.S.: I am aware that this question is valid for any set of narration or story but I'm focused and interested about the scope of movies.
Thanks in advance for any links to proper sources or valid arguments and examples.
