Beware, "The Babadook" is sure to give you nightmares. In this Australian horror hit, a single mother (Essie Davis) grieves the loss of her husband and battles her son's fear of a shadowy monster named the Babadook. As they hear things going bump in the night and see shadows lurking in their house, they begin to wonder whether or not the Babadook is actually real. Like "Get Out," this film is heavy on the psychological horror, but it also uses fear to deliver a deeper message about grief. If you're looking for a horror film with depth, "The Babadook" surely won't disappoint.
