Aurora

Well, I can safely say that in terms of films (even short films) that decide to take a complete 180, this is probably in the top 5.  Eh, okay, maybe top 10.  The animated short Aurora was created by Dutch animator Aimee de Jongh, and tells the story of a woman seeking something mysterious in a forest.  Something rather... otherworldy.  From there, a short series of revelations come into play that are guaranteed to catch you completely off guard. The art style and darker mood was definitely interesting, reminding me of early rotoscoped features that were prevalent during the era of Ralph Bakshi.
