With "My Perfect Stranger" KBS has succeeded in creating a sophisticated genre mix: there is a complex crime thriller that is excitingly intertwined across time and space, colored with its ultimately opaque interdependencies. There is charming time-travel with the chance to heal emotionally troubled family relationships and with the distinctive complexion of the late 1980s in the transition from dictatorship to democracy. There is also the pointed coming-of-age of the protagonist's parents and their classmates of that time. At last, even a (though rather tender, cautious) love story emerges out of the common fate of the two time travelers.

The KDrama thus is presenting (in my opinion) a thorough emotional variety, which has a lot to offer from suspense to amusement an even romantic vibes. So all of this comes rather casually. Well grounded. At a comfortable pace. With feeling, especially around the diverse family dynamics, which are allowed to take their distinct twists and turns from the different perspectives of time and space.

A coherent, harmonious KDrama experience. Worthwhile.
