As for the drama...again, it"s mainly just perfunctory. It"s the bare minimum of plot cohesion necessary to prevent us from thinking "Doctor Frost" has been a complete waste of time, since there are a few important plot points here. Unfortunately the design of this episode serves more to remind the viewer of the drama"s flaws rather than the strengths. The actual ending may or may not be able to deliver on the set-up. In any case I doubt I"ll be very sorry to see the drama go.
"Doctor Frost" is directed by Seong Yong-il, written by Heo Ji-yeong adn features Song Chang-ee, Jeong Eun-chae and Lee Yoon-ji.
