I was attracted to this drama because of the time travel part but I found the story average because there were many instances of plot holes.
I was not impressed by the main character Park Gwang Ho, a detective who doesnโt seem to have a hold on his emotions and seemed rather immature. I found the leadโs acting stiff and bland. The second lead was better.
Most of all, the police seemed very incompetent and at times, silly.
It is nowhere near Signal and canโt even be compared.
