In the movie Rubber (2010) directed by Quentin Dupieux, there's a group of people who watch and do nothing as a tire causes havoc at a motel, but what is the reason for them being there and does this contribute to the plot of the film?
The entire film is a commentary on cinema itself. There are a few different metaphors or interpretations I have heard about the film.
There are plenty of other correlations you can make with the film.
I'm not sure if this answered your question, I hope so.
