I've read some of the reviews and I actually don't understand why some people said they're not satisfied with it . To be honest , I didn't watch the original one but I really liked the korean remake so much .
My favorite genre of drama has been always thriller , action , science fiction etc ..
This kdrama has all of the genres in it : family (between Moscow and Denver) , a little romance (Rio and Tokyo) , action , drama , sadness ...
I don't know what to say but at least I know that this kdrama was so far from my eexpectations in a good way .
The intelligence of each one especially The professor . I loved how he made a plan and didn't forget about the little details .
I didn't finish this yet but I hope nothing bad happend in the end and I wish that this kdrama won't dissapoint me with the ending.
I advice you to at least try watching the first ep and I am sure you'll admire it .
