I haven't noticed much censorship of violence - in fact violence in Korean thrillers is way over the top imho. If it's that bad and it's been censored, I gulp to think of what the uncensored versions are like. But I'm against any censorship, so I vote there's too much anyway. Free speech (should) rule.
I'm already confused just reading the above summary as to who did what and where and what they do now and who is what to whom, not to mention all these brilliant minds just happening to have film-star good looks, not like any doctors I've come across
I've watched 2 episodes and I have to agree with others that the weak spot in this drama is definitely Kim Go Eun. Her acting range runs the gamut from A to B. She'd be more suited to zany or teen rom roles - both of which I unfortunately dislike. I'll stick it out for the nice interaction among the boys. But as you can't really by-pass poor old Go Eun, this is not one where I feel the urge to immediately watch the next episode.
Lost interest, it just seems to be about fighting interrupted by a bit of romance, boring really, don't know if I'll get back to watching, Kim Hyun Joong should stick to singing

There was a problem getting Episode 4, so I had to use elsewhere, you could probably find it on youtube.
