How to evaluate the Korean drama mr. sunshine?

First of all, the cast is quite strong. In addition to several well-known protagonists, there are many familiar people in the supporting roles.

Back to the actor, acting skills pass, lines are good, can speak English, Japanese and French lines. In my opinion, it is a drama that can be watched.
