Maybe it's just been the last two years spent in an academic background, but it seems that a lot of text -- prose, poems, and even movies and plays -- have layers to them that are only noticeable or understood when studied (scrutinized), not when the text is simply read for enjoyment. If this is true -- and maybe it's not -- who does the writers put those layers and subtle subtexts into their work for? Themselves? To prove to others that they are capable of such things? Or do they add something to the text that's not readily apparent to the casual reader but that would be missed by the casual reader if they were absent?
