Basically this is a variety shows that enable you to see how the medical resident's life in South Korea. It covers the life of residents of the Surgery Department, Pediatric, Internal Medicine, and so on.

If you are a medical student or doctors, you would enjoy this and may feel relatable. But if you don't, this variety shows may give you a new insight about doctor's work and life in the hospital in real life, because it's nothing like the life you've seen in those medical drama.

Should you try to watch this ?
I personally would recommend you to try, because there would be a lot of things that may helps you understanding medical field better.
