The film I thought of when watching Deathgasm, a metal in spirit and content horror comedy from New Zealand, is Joseph Kahn’s Detention (2011), in which the ADHD generation is spoofed in a way in which the ADHD can understand. This might be unfair to Howden’s film as Detention is a masterful barrage of sight gags and insanely quick simultaneous layers of smart dialogue. Deathgasm does just that just without the clusterfuck of genres, Deathgasm is through and through a film in which metal runs through its veins.
