Jeremy Saulnier’s Green Room takes advantage of two primal human fears to fill its audience with a profound sense of unease: the fear of confinement, and the fear of being outnumbered in a fight. The film establishes an omnipresent feeling of dread by casting the members of a punk rock band into the deep end of a hinterland Neo-Nazi club. Though the set itself is fine, one of the members witnesses something he shouldn’t, and the film becomes a hyper-realistic slasher thriller set in this single, remote location. Though the story essentially recreates the “Ten Little Indians” trope, there is a subtlety and direction to the plot and a dimensionality to the characters that raises Green Room above the common slasher.
