Great, great medical drama! Great plot, great acting, enough twist, not overdoing the dramatic and emotional part at all, just... enough. The interaction between doctors and patients was really touching, the hunger for power convincing but also leaves room for you to feel sorry/sympathize with the character. Not much romance in this one, but since I'm not a fan of such topic, it didn't bother me at all. If you like serious drama, watch this one. I wouldn't categorize it in either the "dark" drama side (like Byakuyakou, 1 million stars falling) or the "happy" drama side (like Hana Yori Dango), it's just... realistic I guess. Overall it has a sad ending and a vague feeling as you're watching it, but everything in this drama was so raw, so undecorated that just leaves you feeling like you can really meet these people in real life!

OK, fair review.
This drama has good plot, if you can call it "plot". It doesn't really have much "action" (aka unpredictable events) in it, but I appreciate the slow plot (to the point that it was sleep-inducing thanks to the cast) that tried to portray the emotions and reluctance of Ken (main character). However, with a drama driven by emotion/internal feelings like this one, you need a really strong cast to convey the idea. Just think about it. When you're watching an action movie, you're not gonna be pausing for the expression on a person's face for long before the next action scene kicks in. However, in dramas like this where there are long pauses of characters looking at each other, it just puts me to pain how expressionless, emotionless YamaP was, and how Nagasawa Masami, with her trademark big grin, was overacting. Two opposites don't really make a good one in this case. The only thing that kept me watching 'till episode 9 (and after that I just fastforwarded to the special) was the tolerable development of the character.

In general, good plot but unfortunately the cast couldn't fulfill half of what the plot wanted to carry.

First off, some comments here mesmerized me. The first question that pops out is, "Do people think?" OK, Byakuyakou has the two lead casts that are the same in Sekachuu. In Byakuyakou and Sekachuu 1 person dies, 1 person lives (main characters). THAT'S IT. I probably will never understand how people come up with the concept "Byakuyakou and Sekachuu are similar". Well let me ask you, are "Romeo & Juliet" and "Hamlet" similar??? They're both written by Shakespeare after all!!!!
That said, Byakuyakou is a dark drama. I haven't seen A million stars falling, but this is one of the best Jdrama, if not drama overall, that I've ever seen. Yes, its logic has some loopholes, but what kind of dramas/movies is free from loopholes? The important thing is, they tried to portray the connection between the 2 characters, and they did it well. The filming is impressive, the acting is superb. I don't know what else people are demanding from this.

Also some people give this drama a 5 because it's "depressing". If you can't stand dark dramas, don't watch them! Just because a drama is "depressing" doesn't mean it's bad. Many times it's quite the reverse, actually.
