Season 1 was nice and interesting but Season 2 is basicaly just a rerun of season 1. The most absurb point is that President Do is now Chairman Do and then the rerun of feud between Kim and Do.... The story starts to get stale as it ran out of ideas in season 2.
The ridiculousness and unprofessionalism of doctors are just too exaggerated to the point they became just unbearable to watch. Boring and I started to just fast forward to finish Season 2 ASAP. A typical problem with season 2 when audiences expect more from season 1 but dissapointed with lack on ingenuity and new ideas.
