This argument is all about what's good enough to be art.

If the first film ever made was boring, film was not yet art. If the second film was good, film suddenly became art. Including the first film?

Is a really really good film art, or must it be at least really really really really good?

There is no film everyone likes, so the only way to recognize a good film is by majority. Must it be filibuster-proof?

This debate makes no sense.
