I know a lot of people say he was not a good father because of Julian, but when you listen to a song like "Beautiful Boy (Darling Boy)" it's kinda hard to say that because you hear the love of a doting dad throughout that song. And from what I've heard, he did spend more time with Julian in his latter years. You have to remember that he was at the height of Beatlemania when Julian was a kid and he was seeing the world, by the time he had Sean he was more mature and mellow and a better father for that. My oldest brother had a quickie "because she's pregnant" marriage and was just 20 when his eldest son was born. They divorced not long after and he ended up moving because of work and he didn't spend nearly the amount of time with his son and he wished he would've.... then came the second (and current) wife and then he had a daughter and another son and with those he watched them grow up and was a responsible loving protective father the way you expect dad's to be. The difference? He was nearly 30 when the other kids came, he was mature and ready to be a dad while the first son was the product of him being too stupid to use a rubber with his girlfriend as a 19 year old.
