I guess if you dismiss the prequels you hate the fact Hayden's ghost is in ROTJ, but for those who didn't grow up with just seeing Shaw, it might be different, so I showed both scenes to 3 kids and asked them if the Shaw or Hayden Anakin ghost made more sense, 2 of the 3 told me that young Anakin made more sense to them since "the old guy" doesn't look anything like the Anakin they know, my daughter though Anakin would probably choose to look young instead of old, and my son suprised me by saying both made sense to him, I asked him which one made you feel better about the ending he said the new Anakin.
I didn't get into detailed questions about redemption, I just wanted their gut reactions.
