Although I didn't cry until later in the series, this drama was breathtakingly beautiful and sad. Truly it is one of the most spectacular and finest dramas made by Japan. It's not one of the highest rated dramas for no reason. Don't hesitate because this drama doesn't lack much. It is based on a real story and although it deals with the depressing topic of sickness like lots of other dramas, the concept doesn't take away anything from the show. The story was finely written and flows like a ball of yarn rolling across the floor. It had everything, sadness, happiness, youth, and even some breezy romance. You'll learn not just a lot of medical things from the show but you'll also learn the value of a person's existence. The acting of the entire cast deserves a standing ovation especially Sawajiri Erika.The music is very sentimental and mellow which is perfect for the atmosphere of the show. The theme song "Human" by K is one of my favorite songs of all time. As for the rewatch value, I gave it a 6 because I don't think I could rewatch this drama many times like I can for Galileo. The roller coaster of emotions from episode to episode would be too much for me to handle. However, there might be that one Friday or Sunday night, when I can sit back against the wall by my bed and watch an episode of this drama. Overall, great show. Go ahead and watch it. It is definitely worth the watch!
