This. Movie. Is. Golden. The acting is great. The setting is great. The emotional pulls are great. The premise is great. The cast is great. I don't even know where to begin. Perfect cast. Song Joong Ki plays a mute boy, which is in itself the hardest kind of character to play. Everything conveyed in that character must be shown through body language, and Joong Ki NAILED it. I'm sure there were several laughs as some adorable scenes were shot, because it's almost impossible NOT to smile when Cheol-su is learning to wait before eating, or how to tie his shoes. In addition, Park Bo Young does a superb job of showing her character's transition from a depressed and physically weak teen to a strong and courageous young lady. I won't even mention that one asshole. The story itself is something that has probably been done in some shape or form before: one character is raised by animals, and the other cleans them up and teaches them how to be human. But the way that it was executed is different and unique and because the script is so strong, it makes the production as a whole that much stronger (combined with the cast performing marvelously makes it strong enough to withstand having a steel beam fall on it). It was cute, it was fun, it was dark, and it was a roller coaster of "he did not just do that" and "can't you see the truth here!?" The ending was beautiful (though not the way I would have liked it to go), pulling at just the right heartstrings to make you wonder what could have been. I definitely recommend watching this movie.
