This was actually my first Korean movie. I knew the movie by its title and main cast before I actually watched it. This movie was a very popular (and still is) and holds a 100% score on Rotten tomato rating site, which is very good. The cast and acting in this movie is superb. Song Joong Ki is an outstanding actor and the role of a wolf boy Chul Soo is one of his best work so far, especially since the role was mostly based on mimick and movement of the character, with very little dialog. Joong Ki's chemistry with Park Bo Young was lovely as well. The supporting cast was nicely chosen. The story of the movie is moving with an excellent screenplay. The end had me sobbing. All in all the movie is wonderful and I warmly recommend it to any drama lover, especially to those who just started watching Korean dramas or movies.
