This is virtuoso, on-the-edge stuff, as exciting as anything we've seen from the States in ages, and more thoroughly engaged with the reality it describes... The politics of the piece are confrontational, to say the least, but there is a maturity and depth to the characterisation which goes beyond mere agitprop: society may be on the point of self-combustion, but this film betrays no appetite for the explosion. A vital, scalding piece of work.
