I never really thought about it until seeing this video, but Darth Vader's story really does mirror the Grinch in Dr. Seuss' 'How the Grinch Stole Christmas'. A mean, ornery Sith, who's whole bag is to just ruin everyone else's day. Then at the last moment has a change of heart.
How has this not been done before? I can think of no better way to kick off the holiday season then taking in a viewing of this mash-up. It's expertly done, with someone who really took the time to make sure it all matches up and makes sense.
Merry Christmas to all, and may the force be with you.
