I'm going to admit that many people will neither appreciate nor understand this flash, and that there isn't much "animation" per se. However, this style and set-up was necessary for the effect and underlying message of this movie.
As you may have guessed from the title, there is an autumnal theme. However, despite this theme, there is an apparent lack of color in this movie (mostly in gray, black, and white) and hopefully you can figure out this particular choice.
With all that said, I'll leave you with your thoughts.
