I had typed out a response where I refer to the second two paragraphs of my reply above and elaborated on them, but a more interesting thought occurs: what is a sugar-only media diet? How does it differ from any other 'media diet'?

Let's say you'll only ever keep watching if a film begins with an explosion. Surely, if this how the audience behaves, then every film produced will quickly converge on beginning with explosions.

But if every film begins with explosions, maybe you become tired of all the explosions. Eventually you'll come to associate an explosion-heavy start with mediocre formulaic films, and your behaviour will reverse: maybe you'll now refuse to watch any film that begins with explosions.

Surely it's all just an endless cycle of fashions and counter-fashions, culture and counter-culture? The studio gives us what we crave, and we eat it all up until we're sick and want something else, and then some avant garde artist gives us something else, and if it works and is popular then all the studios steal it and the cycle repeats?

In as far as art isn't 'productive' per se - ars gratia artis and all that - to what end should you suffer through art you don't enjoy?
