Samuel, The Babadook (2014)

There’s nothing inherently evil or supernatural about Samuel but he is a very difficult child. His scariness lies in how challenging it is to take care of him, especially as a single parent, which his mother, Amelia, is. He has a very big and rambunctious personality and creative imagination, which result in ear-splitting tantrums, violent outbursts, and the hyperactive creation of homemade weapons. Since The Babadook puts us in the mindset of a mother who is dealing with grief, every little thing about Samuel makes the viewer want to explode in anger or frustration. The prospect of raising a child like him is terrifying; no matter how much love you might have for him, the way he constantly bounces off the wall would be a never-ending nightmare.
