Here's the scenario, Jane a sex-slave android is in great fear that a psycho killer is targeting her in a highly secured Zone 414, we see that it is impossible to catch the killer because even David, the ex-cop and ex-marine, is easily knocked down as the killer possesses cloaking as well as superhuman-lightning fast maneuvering abilities. Turns out that, at the end of the movie, for whatever unknown reason the killer is suddenly defenseless, overpowered and pounded to near death by Jane the sex slave, while David the hero is still rushing to the scene to 'rescue' her, or is it in fact the other way around? This got to be one of the greatest anti-climatic endings. Who wrote the script? Maybe that person should be sent to Zone 414.
