The Babadook (2014)
The Babadook is an evocative and terrifying movie about loss, hatred, and familial strife. The Babadook has been called one of the greatest horror movies of the decade, which may not necessarily be true, but there is something to be said about its creative authenticity and attention to detail. The only deterring factor to this movie is that you're going to want to strangle the child that's on-screen by the end of the movie, which is a perfectly normal and understandable reaction.
