YMMV / The Postman Fights Back

• Complete Monster: Lord Hsu, introduced as a representative of a wealthy baron hiring Ma and his team of couriers to transport an expensive cargo across the wintry Chinese-Mongolian border, turns out to be a Professional Killer and Manipulative Bastard who is using the main characters for a Suicide Mission, killing them off one-by-one in excruciatingly brutal deaths as their journey progresses. His true identity is revealed when he tortures Miss Li to death while having her suspended from her wrists, and later strangles Gui-hua, Ma's girlfriend, and eliminates Fu Jun in a fierce battle. In order to enforce loyalty from the main characters, he abducts the kid sisters of Yao-Jie, the youngest member of the team, forcing Yao-Jie to become The Mole to ensure the cargo would arrive at its destination in exchange for his sisters' lives, only to reveal the cargo to be a heavy machine-gun which Hsu demonstrates its effectiveness by using it to kill twenty innocent prisoners before firing it upon Yao-Jie and his younger sisters. A sadistic Blood Knight, Hsu is perfectly content with starting a War for Fun and Profit not caring how many people will die as a result.
• Moral Event Horizon: Hsu may have plenty of Evil Is Cool moments due to being a ninja, but when he deliberately guns down two little girls barely 6 years of age he pretty much lose whatever cool points the audience may have for him.
• The Woobie: Its hard not to feel bad for Yao-jie, who is forced to become The Mole, only because both of his sisters have been captured alive by Hsu as a leverage. Worse of all, Yao-jie ends up discovering he's been used by Hsu to transport a weapon of mass destruction, and witnesses the weapon being used to kill off two dozen helpless prisoners, which he is partly responsible for against his will, causing him to have a My God, What Have I Done? moment. And when his sisters have been freed and he's allowed to leave, Hsu changes his mind in the last second and guns down Yao-Jie and both the little girls in a horrifying Kick the Dog moment.
