I wanted to give this show a ten but refrain because one thing still grated my nerves after I finished watching. The part about how a time portal existed out of nowhere and somehow was only active for the main character. That part was just left up the air. I didn't like that.

Other than that, I loved this show. Plot and characters were both good. Choi Jin Hyuk is so very handsome. And such emotions when expressing despair for his wife and child's whereabouts. Great actor.

Music: Loved the OST. A 10+.

Rewatch - Yes.

Overall - great show. good ending. Glad it wasn't left open like other thriller dramas.
