It's an ambitious task producing a science fiction movie on an obviously low budget, especially if the content focuses on condition rather than plot.
The movie's cinematography is well worth watching, also editing is well made, but without a straight plot, scripting has to carry a heavy load because every scene has to stand for itself. Unfortunately, it doesn't hold up to the task. Though the dialogues seek philosophical depth, they lack refinement, constantly throwing me out of the suspension of disbelief.
Acting is just fine, including that of Ryan Kwanten who plays the lead role of Jack. However, his sloppy diction is hard to take. Eager to be as authentic as possible, he sacrifices his control over speech which makes him simply hard to understand.
Also, there are too many references to "Blade Runner": A lonesome killer seeking love, voiceover narration, androids, the lifespan issue, an Asian future city, even the soundtrack that sounds like Vangelis at times - there are just too many parallels.
Great Hong Kong footage, good editing, but overall an overambitious undertaking.
