One of things conspicuously absent was Anakin being "seduced" by the dark side (as Obiwan put it in SW). When I think of that, I think of the thrill the emperor seems to get by zapping people. There should have been some sort of hypnotic appeal or addiction to the dark side -- sort of like the effect of the ring in the Hobbit and Lord of the Rings. But in the PT, Anakin never seemed to enjoy anything about the force or its dark side - mostly he was in agony, not being "seduced" by the dark side.
