In Episode 1, when Maul gets cut with the lightsaber, he gets cut in half. In Episode 4, Darth Vader strikes Kenobi down at about the same level, place and height as Maul, about waist high. Either they should both disappear, or they should both be cut in half, what gives? Other than obvious reasons that special effects were upgraded a lot since the 70's, I want to make sense of this from a narrative point of view. Edit: didn't see the questions thread, I'm sure this can be merged though, a lot of forums can merge new threads onto existing ones.
