I just recently watched Starwars episode 6.... (BTW, IF YOU HATE SPOILERS, DO-NUT READ THIS! Just saying, for your own benefit.)
I hate to admit, but i did shed a couple tears when Luke was holding his dying father in his arms. That was the first time i ever... EVER actually cared about Anakin. I wasn't really a big fan of him. Anyway, vader reminded me of... get ready for it... Nightwing, i never cared for the evil over-stallion until he lost his first son. I wanted to cry out to him and comfort him, until he rejected Star's offer to help. My compassion on vader was the same for Nightwing. Star reminded me of Luke, Vader's rival, Nightwing's rival.
