Nancy Allen, portraying "Lewis," appears to be among the few actors returning from the initial film, and this installment marks an exceptionally poor end to the story. Dan O’Herlihy evidently found the writing unsatisfactory, leading him to relinquish control of his technology firm ("OCP") to the considerably more severe "Casey Wong" (Mario Machado). Wong then employs Rip Torn, playing “the CEO,” along with his military associate "McDaggett" (John Castle), to discourage what remains of the Detroit police. The intention is to substitute them with a group of criminal operatives—dubbed the "Rehabs"—and to transform the city in a manner reminiscent of Nero’s destruction of Rome, envisioning a modern cityscape rising from the ruins. Fortunately, the protagonist, a hybrid of man and machine, intervenes to oppose this nefarious scheme. While there's an abundance of action sequences, the scriptwriting is excruciatingly awkward, the performances feel stiff, and any originality present in the 1987 film has vanished. It’s a blatant effort to exploit a franchise nearing its end, representing neither a high point for those involved on screen nor behind the camera. Ultimately, it constitutes an appalling misuse of film stock.
