Despite some heavily loaded exploitation of middle class fears of irrational terrorist violence, this movie achieves a certain bulky conviction of its own. After the pointless slaughter of his family in Naples, the cerebral war-games of a NATO electronics expert (Kennedy) are undermined by baser instincts of revenge. Thrashing around like a stunned ox, Kennedy takes on the extremists single-handed, finally wiping them out after they take over a crowded supermarket. His disintegration into a brute force gives the film its momentum, and more or less everyone stands back in disbelief to let him get on with it. The computer hardware is diverting, and treated with greater respect than the terrorists, who are given no credibility whatsoever, ideological or otherwise.
