It (2017)

A group of seven children in the town of Derry, Maine are considered misfits and form a group called the "Losers Club." They soon come to realize that they've all had encounters with a demonic entity that appears in various forms, but primarily in the shape of a clown.

Not knowing what to call the entity, they refer to it as "It" and believe It is responsible for the recent murders of a number of children in their town.

Based on the novel by Stephen King.
