Interesting, and that's a gross understatement.
With just a basic knowledge of the events of WWII and those surrounding it, i found the animation to be very satisfying in the fact that i recognize a lot of it. The pictures may not have been drawn to painstakingly awesomeness, but that's not what this required. It almost hearkens back to the day when this kind of drawing would have been considered cutting-edge technology, if not unheard of.
All in all, a great tribute, and the song's great to boot. I watched the trailer of that movie a couple times over, heh. The movie i heard wasn't that good, but the song was awesome. Keep it goin.
