If Lucas had hired just one person half as invested in the OT as we are, the prequels would be so much better for it. Just someone to say "Obi-wan said that Yoda trained him" or "Leia remembers her mother" or "Obi-wan kind of needs Anakin's lightsaber".

I think many persons told him things like that during the making of the PT but he just did not care much, or came with quick cheesy answers and the people in front of him did not have the guts to say no.

Personaly I'm sure Lucas did not forget about those little lines from the OT. He just wanted to make a script around new things (and why not?) but he has gone too far, and he had to fill the gaps but it was too late. At least that's the way I see it.
