It is my first time watching Kim Soo Hyun (he reminds me a lot of Apo from the KinnPorsche show), I am very impressed with his acting. You could easily tell the characters he played apart by their mannerisms. I understand the story and it is definitely unique but I just wish it would've focused more on the story/plot and less on the mimicking process. It was pretty obvious what the one guy was doing half way through the movie, I feel like the actual story should've started coming together by then. The movie was over 2hrs, I think there was enough time to explain everything "behind IT" but instead the ending was rushed. I have many questions, especially how, who and why?...
The visuals were very nice. Sulli was very pretty. The actors were good, just a very poorly put together story/plot.
