Watching first half of this movie I made myself to write- Being accustomed to enjoy super power of superman, I did not like his crazy behavior in this movie. And in the getup of a documentary producer Jun (popular heroine of "My Sassy Girl", "Daisy" etc) seemed to be a bit rough also. But at the end of the movie the total concept simply wowed me. Really in this self-centered society any individual can turn out to be a superman just by exercising his humane qualities. Although their presence seems to be rare, they can help and inspire countless people effectively. And their motto is simple- "Strength doesn't open big iron doors but a small key will and we all have the key inside us to open the door to a new future." Both the main actor and actress did their best and really such a great realistic movie's worth watching.
