I've mentioned before I love anthology horror, and this movie does a decent job in presentation and execution of five overlapping tales. This movie doesn't have much of a linking narrative, as we simply drift from one tale to the other over the course of a day on a small stretch of highway. There are quick reveals that the setting is 'off' as there are supernatural guardians at the borderlands, and radio sermon playing between credits that seem to both speak personally to the characters and to fill in the blanks for the audience. Not that all the blanks get filled in as this movie never comes out and overtly answers questions, but the viewer can certainly draw their own conclusions. Like with any anthology, the themes and quality of each tale varies, with one going for tension and suspense, with another more about body horror and gore. There's an obvious connection between the tales that will be quickly apparent if you've ever seen a horror movie before, but this was quite well executed.
