Story: This was my most favourite Korean movie everrrrrrr. I don't know why, but I just fell in love with it. The story was cute, funny, sad, heart wrenching and very emotional (for me anyway). Of course the story was very unrealistic, however it was very believable (and made me wish I had a werewolf boy too). Acting/Cast: The only thing I need to say is: Song Joong Ki. The end. Great actor, I know, I know. He is a pro at capturing the audience's heart. He was also a pro at playing a dog boy, like unbelievably pro, to the extent of almost being a dog boy. I think he is definitely what made this movie so great for me. Of course the female lead was also nice and helped to make the movie great... but Song Joong Ki is the winner. Music: It was nice. I don't really remember it that well... but I never do really remember music from movies. All I know is that if the music wasn't good then the movie wouldn't have been as great as it was! Rewatch? Yesssss! I think I watched it three times in the same week I first watched it. I had to show my whole family. Even my sister who dislikes watching Korean movies and dramas cried and fell in love with Joong Ki. No joke. Overall: This is THE BEST Korean movie (in my opinion). I'm so glad I watched it. It was so nice. I may have lost many litres of tears in the process of watching it, but it was worth it. I recommend everyone watch it. It will only take 2hours of your life and I doubt you will regret it and if you do, I'm sorry that you didn't like it. YES watch it.
