HARD REVENGE MILLY is a cheap and cheerful Japanese sci-fi/gore effort, shot on digital video and clocking in at just 45 minutes. Most of the film was shot in some abandoned warehouse somewhere and the film generally has an amateurish feel to it. However, it's a million light years ahead of the Korean TEENAGE HOOKER BECAME A KILLING MACHINE, which is one of the earliest of these 'Asian machine part girl' gore flicks.
The storyline is a simple story of revenge with a small cast and little acting ability to distract from the violence. A girl is attacked, mutilated and left for dead by a gang of thugs, her family slaughtered. Somehow she comes back to life, animated by machine, and goes to wreak vengeance on those responsible. The narrative is limited and there are a lot of holes, but this isn't about the story.
Instead, it's a film that seeks to serve up as many gory deaths as is possible within the slim running time. Bodies are hacked up, heads are severed, and there's an extended martial arts battle to end all battles. Japanese blood sprays abound, and it all looks very fake and unbelievable, but it's kind of fun nonetheless. A feature-length sequel, HARD REVENGE MILLY: BLOODY BATTLE, would follow.
