"My father is truly dead" may be the best line in the Original Trilogy. Not only was it a great burn, Vader's subtle actions made it very clear how much Luke's retort hurt him. Really foreshadowed his eventual redemption.
It was, just seeing how visably hurt Vader was from that quote despite his mask covering his face and such really sold me on how much vader wanted to bond with Luke and such.
Yeah...great movies. I hope Disney releases the unaltered originals. There's some rumors going around, including, supposedly, someone asking the head of that division at DIS, and his response was "yub nub." So there is hope.
