Review: LFF 2016: Free Fire

Remember that sequence in Spaced, where Tim gets out of a bind by initiating a pretend shootout with finger guns, safe in the knowledge that no one in the near vicinity can resist joining in? Ben Wheatley's new trigger-happy triumph plays out exactly like that, complete with stylised slow-mo, only with real guns, real bullet wounds and with it all carrying on for a real long time.
