I've been crital of Park Shin-hye's acting in previous series (Memories of Alhambra and The Heirs), but she was excellent in Doctor Slump, both in comical and dramatic scenes. She looked so beautiful, too! There was great chemistry between her and Park hyung-sik. His comedy scenes were hilarious; he has good timing. Good comical scenes in every episode. I enjoyed Yoon Park' charactor, good part for him. The whole cast did great.
Good storyline, handling a serious theme well.
