I more prefer the first season, but can't lie that this drama is a masterpiece. The surgeon scenes feels so real and the plot twist (in some eps) is more better than the first season. But it kinda disappointed to see the surgeon scenes has more dramatical effect than the first season, and it make it less realistic, that's why I prefer the first one. Also, I read the official preview from TBS' site, it describes Amagi as "completely opposite" person with Tokai, but when I see them, I think they had more similar characteristic rather than "completely opposite". But it still really worth to watch & rewatch!
