Points for....
Originality
Ambitious and complex story
Good cast who portrayed multiple characters, time periods and a wide range of emotions
Not using stupid misunderstandings to create conflict
Not dragging this out to too many episodes

I did like this drama, but the back and forth on the time travel wasn’t completely clear (not sure all of it made sense) so I stopped being logical and just watched for the emotions at the end. (They don’t follow the time heist rules for time travel.)
