Great show, Jang Hyuk delivers again. I loved his performance and I was so invested in the struggles and triumphs of his incredibly compelling character. His power and range as a performer is just mesmerizing. This works really well as an intense sports story, a beautiful and heart wrenching family drama, and a gruesome medical thriller. Really liked the characterizations of the second ML and the villains. Once I started watching this I couldn't stop. The only thing that didn't fully work for me was the characterization of the wife in the second half of the drama. She became placid and bland and faded into the background too much as the story progressed. I would have also enjoyed more scenes between husband and wife fleshing out their dynamic more.
