Consistently engaging as the story is told entirely through self filmed home video, police body cam, security footage, and onscreen texts. We feel so bad for the woman and children who wind up brutally murdered, and judge the man who did this from the beginning. There’s never a legitimate question about what happened, and the only tension is ramped up with information withheld from us. Stylistically, this is almost the documentary version of Unfriended, and for that, it’s unique and new.
