I watched the last few episodes just to finish the series. It was boring, and the chemistry between ML and FL was very weak. Everyone acted like it was the ER from "New Amsterdam Hospital" :P
The show isn't bad. But ML's wife is incredibly irritating. How on earth (and why?!) did she survive in Canada? What did the trip to Toronto do for them as a family? Because, as you can see, besides learning the language, NOTHING. I don't understand this korean obsession with sending their children to America.
I think the topic of relationships between Koreans and Japanese is still a sensitive one (due to its complicated and painful history). I feel like the director was treading on thin ice :P
