Part of the Great Awakening to realize that so many of the "stories" we remember from childhood i.e. Grimms Fairytales, could have actually come from real events. This evil sh*t was going on in Germany then and the people knew it. And more recently, Eyes Wide Shut which is more of a documentrary then we ever could have imagined. Still trying to process all of this myself and I'm sure many others are as well.
