The film embodies the story of members of the Rock Band and a powerful young woman embarking on a new path in their lives. Everyone began to engage in fierce fighting for survival. They are fighting against a group of obsessed capillaries after watching a serious murder in the city.
Green Room may be perceived as needlessly and excessively nihilistic; instead, Saulnier's film is gloriously unpredictable, a unique thriller that rips up the rule book whilst paying deliriously gory tribute to it.
It takes a while for the solid premise to unravel...and for the better portion of its running time Green Room functions as a highly effective thriller.
[Saulnier] has a gift for creating nail-biting tension and gets superb performances from his cast, but storywise he paints himself into a corner from which he can't escape.
