I still find this drama very good so far. The medical stuff are not that heavy but still there and the story remains interesting and very heart-grabbing. The hospital conflicts seemed to decrease in the recent episodes and there's a lot of highlight on Si On regarding his family, his feelings with Cha Yeon So and him overcoming his disability. Professor Kim Do Han's finally seemed to accept and train Si On as a surgeon and it's a good thing that he even knew Si On's past now.
@Me Maria, I have nothing to add, so I'll just agree too. :)
