Read the making of revenge of the sith. In it it describes how lucas was in fact considering making anakin the son of palpatine by way of midichlorians. Imagine that, palps is actually Luke skywalkers and leias grandfather. creepy huh?

Seriously though, i does take all the mystery and mysticism out of it all. I even think if Joseph Campbell were alive he would tell lucas it just ruins the mystery. By the way he thought the original star wars films were wonderfull. And that was long before the special edition or prequels, If they were good enough for old joe then they are good enough for me.
