My interpretation was - even in such forsaken place, people find their differences and inability to reconcile, to forgive. They can’t escape it, so their confrontation grows into this absurd standoff of forced friendship and desire to be left alone. The scenes of desolate shorelines and bleak landscapes invoking agoraphobic feelings accentuate that theme. It’s an Art House film, frankly one of few good ones I’ve seen since the Lighthouse with Willem Dafoe (minus supernatural elements).
