There's spooky visual scenery, including a decrepit mill and a bus stranded in the dark.

The subject of sins and regret for sins may upset some viewers. We also see that even characters who express genuine remorse, or who committed no sins (a little boy) are pursued by an assistant, as well.

A little boy has his fate left unknown at the end of the film. He's presumably killed, as the film cuts off before anything can be explained.
