Nonsense. The Skywalker genetic bloodline is right there in the holy OT. Thus, you would undermine the OT not by including such a thing, but by throwing it out. It's part of Lucas' concept and exists in both trilogies. On the part of Sith, or those in the process of becoming Sith. A Sith-like philosophy being expressed by such characters is only what we would expect to see. Should there have been no Sith in the PT? Was Anakin's turn to the dark side something reasonable people should have expected to see in the PT?
