Verdict: Looks like a spin-off from "My Sassy Girl" with some idea from Doraemon

This movie tells about a robotic woman from the future, traveled to 21st century in order to help the guy and also saved the lives of many people.

The ending is a good one but overall the story isn't convincing - because if changing history is possible, the robotic woman may not exist in the first place (well, I guess to further extend this argument, one may be interested to refer to "Parallel universe" in wikipedia)

Rating: 6/10
