Furthermore--how the fuck does the PT suddenly add emotion to a "hollow" scene? What we learn in the PT--the particulars of his downfall--have almost no bearing on the ROTJ scene. The ROTJ redemption is powerful because its an evil man brought to goodness by his sons suffering--learning how he turned to evil in the first place (he wanted to save his wife from visions of death) does not really add anything to the specific scene, nor transform it from "hollow" to "emotional". We know that Vader was once a good man named Anakin who was a heroic Jedi and turned bad--we don't need to know anything more to make the scene work. In fact we don't even need to know this--the scene works because its a man who was the villain sacrificing himself in the name of good.
This is just a fucking stupid argument Go-mer.
