Marvel's Avengers – is very marked. I don't believe that the fact this massacre happened during the Dark Knight Rises rather than the latter is merely coincidental. Both deal with the battle of good and evil, but in very different ways. In fact two different kinds of imagination are
involved. In order to understand this we need to look at the relation of art to entertainment to pornography.
Art can deal with any kind of subject matter, but the way it does so matters. Great art deals with its subjects in a great manner. Commercial entertainment is both (usually) crasser in its methods and more limited in what it encompasses – essentially, subjects with mass appeal, in order to maximize profit, but with certain limits, pornography being one. But the boundary between them is hard to define, or rather hard to agree upon. The most successful entertainment is often a work of art, and of course both art and entertainment may contain elements or notes of pornography (art may even deal explicitly with pornography as a topic).
The human imagination mediates between the senses and the intellect, or the world and the spirit. It can therefore face in two very different directions – call them up and down. Facing "up" it is open to the light of the spirit, and reveals a world of forms shining through the images it constructs. An extreme example would be an icon or work of sacred art, which acts as a window towards the heavenly world that is more real, and more eternal, than the everyday. But any great work of art, I would argue, does this in a way. For example A Child Consecrated to Suffering by Paul Klee, which bears relatively little relation to naturalistic forms, may help to reveal a spiritual essence more effectively than a photograph or naturalistic painting, or a work by a lesser artist.
But what if the imagination faces "downwards"? In certain types of surreal art (though not all) and also in pornography, whether of violence or sex, images drawn from nature are blown out of proportion and arranged in such a way as to turn the soul away from the world of the spirit and introduce it to something baser, more corrupted, and more dangerous – also something less real than the world around us. The effects on us as consumers is rapidly apparent.
