以拍摄喜剧走红影坛的快手导演朱廷平在本片仍维持抄袭西片的习惯，在这部大制作中有十多个片段明显地具有西片的影子。拍得较认真的是本片介绍各个女主角身份的序场，能掌握住精简有力的原则。七个大牌女星汇集一起，赋予她们各人完全不同的新造型，这是本片最大的噱头，也是对观众最有吸引力的一点。首席玉女林青霞扮演一名独眼的匪首，带着六名女将去捣毁日军的"生化城"。其余六位是：一头黄发扮相怪异的神枪手杨惠珊；机灵却胆小的扒手彭雪芬；整天烟不离口的烟枪叶倩文；没酒就活不了的东洋女侠刘皓怡，打扮花枝招展的妓女程秀瑛；和像泰山般打扮的力度山徐俊俊。一向扮演英雄的梁修身，在本片中则演反派日军军官。这在当时台湾影坛可谓是空前组合。本片不足之处是后面拍得马虎，被描述为铜墙铁壁的"生化城"却只是一个仿古装片的山洞，明显地偷工减料。

Fraught with over obvious symbolism, Hartley's early feature is nonetheless a joy to watch. Hal here shows us his uncanny ability to cast his characters perfectly came early in his career.Adrienne Shelley is a near perfect foil to herself, equal parts annoying teen burgeoning in her sexuality (though using sex for several years); obsessed with doom and inspired by idealism gone wrong she is deceptively – and simultaneously – complex and simple. Her Audrey inspires so many levels of symbolism it is almost embarrassingly rich (e.g., her modeling career beginning with photos of her foot – culminating her doing nude (but unseen) work; Manhattan move; Europe trip; her stealing, then sleeping with the mechanics wrench, etc.)As Josh, Robert Burke gives an absolutely masterful performance. A reformed prisoner/penitent he returns to his home town to face down past demons, accept his lot and begin a new life. Dressed in black, and repeatedly mistaken for a priest, he corrects everyone ("I'm a mechanic"), yet the symbolism is rich: he abstains from alcohol, he practices celibacy (is, in fact a virgin), and seemingly has taken on vows of poverty, and humility as well. The humility seems hardest to swallow seeming, at times, almost false, a pretense. Yet, as we learn more of Josh we see genuineness in his modesty, that his humility is indeed earnest and believable. What seems ironic is the character is fairly forthright in his simplicity, yet so richly drawn it becomes the viewer who wants to make him out as more than what he actually is. A fascinatingly written character, perfectly played.The scene between Josh and Jane (a wonderful, young Edie Falco . . . "You need a woman not a girl") is hilarious . . . real. But Hartley can't leave it as such and his trick, having the actors repeat the dialogue over-and-over becomes frustratingly "arty" and annoying . . . until again it becomes hilarious. What a terrific sense of bizarre reality this lends the film (like kids in a perpetual "am not"/"are too" argument).Hartley's weaves all of a small neighborhood's idiosyncrasies into a tapestry of seeming stereotypes but which delves far beneath the surface, the catalyst being that everyone believes they know what the "unbelievable truth" of the title is, yet no two people can agree (including our hero) on what exactly that truth is. A wonderful little movie with some big ideas.
