I find this movie quite interesting. Yang Mi's acting here is way much better than some of the series that she has acted in. I actually like the tough Yang Mi compared to a few previous shows I watched of hers that is like a weak female. She also doesn't sound that high pitch and softie in this movie either. If you are looking for some action and mystery and thrilling + excitement and you find the synopsis to your interest, then this would be an interesting first watch. There are a variety of action, suspense and not to mention sad moments.

I was definitely watching with gripping "omg what will happen after this" moments but I will say that I bawled my eyes out seeing how the guide dog died. That was heart jerking and my extremely in need of alot of tissues moment. But other than that, it definitely is a recommended movie for people who love action and thrillers.
