This drama although the actors were good it was just too confusing.

The storyline was too confusing for me jumping between the past, future and present. There was not much distinction with the actors in each time zone.

I did like the general idea of the story line and understand that it is quite hard to pull it off, they did have factual information on the scientific aspect but yet again confusing.

I wish I did get a ending which look at the romance of the main character but I am aware that it is not a romance.

It did take me longer to watch than other dramas and would not rewatch, but glad I did see it.
