This is a rare move for me, recommending something like this. I'm recommending that you read (at least some of (or even just watch the video embedded in)) Ian Brown's
"The Boy in the Moon". It's about his son, and his relationship with his son, and things like that. Also: fucked up genes, the arbitrary nature of this godless world, the place of love in such a world, etc. It's neither the sentimental 'life will test you' liteness of daytime television, nor is it so grandiose, so removed from the cliche it isn't, as to obscure its own purpose.
