Green Room (Jeremy Saulnier, 2015)

A young punk band find themselves in hot water after stumbling across the aftermath of a murder at a gig for neo-Nazis. Their hosts then set about trying to kill them by any means at their disposal.
The griminess promises the genre norm of messy killings and a low survival rate for the protagonists, and Green Room duly obliges. Patrick Stewart, essaying some kind of accent, comes in out of the blue as the leader of the supremacists and his casting against type is an interesting choice, and the execution overall is certainly more efficient than what the warring parties manage. But really it's just about the body count, as is usually the case with this template.
