Actually, the drama is more of a medical genre with emotional touch and lack of continuation plot.
Plot- I really liked the story, emotions, all the artists who made this drama a masterpiece. Though everything is well off written, it's just that the plot became too dull as it only contained repetition of surgery scenes, plotting and competition among surgeons and set backs in the life of surgeons.Though it was motivating but sometimes became too boring as some scenes have been forcibly put up to lift up the emotional sense but didn't get the timing right to put these scenes. Also, the summary was written about artificial hearts but the story about it didn't progress until the end.
Cast- The cast were perfect in their job with no exception. Each character has a meaning and helps in story development (except one or two). But that too comes under those forcibly put up category so I understand.
Music- The beginning and ending OST's are much of soothing kind especially when they come with scenes. So I really really liked and will make them my playlist songs.
Re-watch value - Definitely i would re-watch this because as a Science graduate i could enjoy the movie whenever I feel like watching these.
If you are looking for a romantic drama this wouldn't be in the list as I feel it's all of a low touch romantic medical drama. The life of female cardiac surgeon standing high in the field full of male surgeons is all about this drama. Can give it a try as you won't regret it.
