This animated movie has been useful to me for my entire life. As a kid, I loved the cartoony parts and the scary parts; as a teenager and young adult it was the ultimate stoner movie, perfect for smoking a joint and watching from the balcony (yes, in those days a few theaters still had balconies); and as a middle-aged crank, I am fascinated by the beauty of the nature sequences. And the funny parts are still funny. I also recommend Bambi and Sleeping Beauty for stunning visuals and brilliant art direction.
