And how is that mode of expression anything higher than selfish indulgence?

In cinema that sentiment has resulted in some of the most vapid, unwatchable trash ever created. In music this results in experimental, unlistenable noise that never seems to appeal to anyone enough to be self-sustaining. It's like an emotionally repressed teenager crying out, "you don't understand my pain, man! you'll never understand!" We do understand, we've all gone through it, and we've moved on.

If DF's creators want to be avant garde, then fine. But it is a lonely, and possibly pointless path, and again a damn shame, because oh how amazing it would be if it weren't!
