Story/Plot: One of the more rare serious time travel c-dramas. I think this is actually the segment, where the drama could have shine. It had an interesting and mysterious start, but unfortunately couldn't maintain it.

Acting/Cast: The cast was kinda average and bland acting wise. Especially the female lead was lacking with face expressions.

OP: For time travel or historical drama fans, it might be worth to have a look into it. The drama really had some potential, but too many weaknesses either in production or cast. So you might drop it after few episodes.
