An accident strands a young woman on an island. As she practices means for survival, the stakes are raised when she realizes she's not alone. Written by Alex Hyner , Alex Theurer , and J.D. Dillard Directed by J.D. Dillard Without question one of my favorite viewing experiences this year, Sweetheart plays as a meticulous course in minimalism. This execution is wildly successful. Jenn (Kiersey Clemons) is immediately thrown into a nightmare scenario with the backdrop of an invitingly, serene island. Her terror and capacity for resourcefulness is sound and enthralling. But as genre does, the wrench in any composure she may be hanging on to loosens entirely as a threat lurks.
