The Babadook. One of the best movies I've ever watched. It's classified as horror but that's just the surface. This movie is really about mental illness. Grief, fear... The Babadook is a type of demonic entity. That completely takes over a woman and her son. It Shows that fear lives inside all of us. And if we let it, it will consume us. We must learn to put our emotions where they belong and face our fears if we want to be at peace.
