There's nothing more terrifying than an army of rollerblading teens chanting and weeping to white supremacist rhetoric.
Japan poaches our ivy league colleges. Germany buys Poland. A rollerblading gang of white boys wearing white trench coats bring The Fear to the weak and marginalized. Patricia Arquette dresses like a cowgirl, grunge sk8r, and ex-member of The Addicts 'cause this is The Future and clothes match personality okay? Dunkin' Donuts exists on the West Coast for some reason. Also NIN carousel parties and pizza delivery still exist amongst the racist rubble and prison camps and terror squalor of New Venice Beach, GOT IT?
Basically, this movie is like an alt-right (neo-Nazis, let's be real) wet dream of Aryan youth digging their rollerwheels into the neck of minorities and the poor and ill and unprivileged. A once ridiculous dystopian premise has become a waking nightmare. Stop the world I want to get off.
