My Mister Just about everyone involved with it says it is the best project they've ever done, and are so proud of it. Every episode builds off the preceding one in a kind of seamless beauty.
The only bad thing is that it has spoiled me for K-dramas, as I keep hoping for a My Mister level of brilliance, but nothing else has ever come close.
