This drama was pretty epic with insane plot twists and realistic acting. For me this was perfect, because of four reasons:
1) I like medical dramas
2) I like good action sequences
3) I like good realistic romance that does not disturb the main plot
4) Big fan of fictional plots especially disaster situations.

So if all these pointers are also what you are looking for, you should really go ahead and give it a watch with an open mind. All the characters were given a satisfying ending leaving practically no loose ends. Happy that there were no long and dragging "go back to the past" sequences and just enough to keep the story going. This plot made me emotional, shocked me, made me hate some characters and later rethink my hatred for them, reminded me of a disaster I've been through and yes, it was one hell of a roller coaster ride that I binged within 24 hours without having to forward much.
100% recommend watching it!
