Good medical drama with excellent acting, especially Ahn Hyo Seop, Lee Sung Kyung and Han Suk Kyu. Other characters are also nice - special mention to Dr. Bae, Dr. Yoon and Eun Tak. Romance takes a second hand in this series. Importance is given to the hospital, doctors and the politics involved. Hoping for a season 3. :-)
PS: No need to watch S1 to watch S2.
