i watched this drama because of so ji sub and wow! worth it. he is a great actor. even though i hate dramas that have a tiny bit of guns in them. see i thought it was a medical drama which, don't get me wrong it was, but in a flash of a second it turned into a war drama. yeah a real war, okay something close. but i still loved it. however i think the villains didn't get a good enough punishment. if am too rewatch this one i will probably watch the first eps before it got dark. but i loved it
