This is the kind of movie I could see being remade by Hollywood someday. It's given to the biggest leading lady of the year, it under-performs at the box office, and her career is never the same after that.
On the positive sides, the movie looks expensive. The sci-fi tech is sleek and the effects look very good. Lead actress Yang Mi does an excellent job. Especially after the time jumping starts. Unfortunately, this is a very dumb movie. It has every movie trope ever. It's very predictable. It has plot holes on top of obvious plot holes. It also misses the "so bad it's good" mark by taking itself very seriously and looking like a fairly expensive. Only the most forgiving and easy to please sci-fi would enjoy this.
