The story is based on a manga series about how an inflatable doll came to life one day and explored the world around her.
Special effects was great and the performance by Bae Doo-Na was excellent but his "Maborosi" and "Still Walking" had a bigger emotional impact on me! I have also seen his "After Life" and "Nobody Knows" and I thought this was one of his weakest works so far. "Still Walking" is available to watch for free at the Japan Creative Center.
