The Babadook

A single mother realizes that her child, while extremely intelligent, doesn't play well with others, and so she withdraws him from school and accepts the fact that he's probably going to seem a little strange until he's older. She is relieved that she herself doesn't have to pretend to be normal around him. After an incident at her niece's birthday party, she finally understands that her sister is a shit human being, and that her sister's friends are shit human beings, and that it's okay not to spend time with them. At the same time, a creature called the Babadook has been caring for her next-door neighbor, a sweet lady who has Parkinson's. The Babadook has fallen in love with the single mother and tries to connect with her through a picture book he has drawn for her son. Gradually they become closer to one another while she works through her trauma concerning her husband's death. She lives happily ever after with her brilliant son and her monster boyfriend.

( this is totally what happens, and nothing anyone says will convince me otherwise )
