The End Of The Fucking World (2017)

The fact that Alyssa and James are both teenage outsiders is enough to form a bond between them. James has been actively testing the thesis that he's a psychopath capable of murder, while Alyssa has been dealing with emotional issues in her own home. But the friendship becomes strong enough that James agrees to go with her on a road trip to find her father. James' worried father calls the cops after them, but they find themselves in over their heads, and a path of death and destruction is soon following in their wake — and leaving an obvious trail for the diligent authorities.

The End Of The Fucking World is a comedy movie directed by Jonathan Entwistle.
