The anarchic spirit of agitprop pulses from this scrappy, smart, subversive film.

It's a heady time capsule and a corrective to the formal timidity of recent political cinema, even if the film's radical vision seems to uncomfortably presage the subsequent fragmentation of the left.

With Borden's work is thoughtful agitprop born of an unfortunately enduring urgency, an electrifying sonic and visual collage that reminds us that continuously fanning the flames of revolution is what keeps them alive.

Rough, urgent and fiercely creative, Born in Flames remains a fascinating film, even if its unrelenting didacticism sometimes blunts its considerable power.
