I don't see any "devil" in the ensemble cast plot. Why is the movie titled "The Devil all the Time"?
With the continuing occupation of Afghanistan overtaking Vietnam as the longest war in American history, The Devil All The Time's unsparing critique couldn't come at a better time. As the film's title tells audiences, Arvin's father spent his whole life fighting because the enemy killing him was at home in America all along.
The Devil All the Time stays true to its title in its embrace of constant darkness and shows viewers only the worst that humankind has to offer — meaning audiences hoping for a glimpse of humanity or a purpose to the madness are shit out of luck.
While the presence of God is a nebulous thing in this backyard fried noir, ‘the Devil’ of the title is present to just about every character inhabiting Pollock and Campos’ vision of Knockemstiff, Ohio and its surrounding areas: It is the hell they make for themselves and their heirs by pretending to be better than they are while ignoring the pain underneath.
