The subject of toxic masculinity has been around the pop cultural block so many times in recent years that — as the topic of a film at least — it’s starting to feel a bit tired. But leave it to Australia, a country that has produced a heroic number of twisted films, to deliver a new and disturbing exploration of this oft-explored idea with Birdeater. The film is the directing debut of Jack Clark and Jim Weir, and the Aussie duo fairly drowns us in atmosphere, pulling visual and aural cues from horror and using them to tell a nerve-jangling tale of emotional abuse, gaslighting and, most importantly, cruelly manipulative and dangerously laddish male behavior.
