I was so happy to see Song Kang play in another drama after LA2,because that one was a tragedy.
He was the only reason why I started watching this drama in first place. After watching couple of episodes, I lost my interest completely.

The story was intriguing at first, and then it became boring. Way too predictable, we have the typical k-drama story which has been already done before, and we are basically walking in circles.

You can wait and see if the old man(which is basically the highlight of this show, but sometimes is annoying) with no prior experience will end up living his dream, watching the young ballet dancer losing his hope and spark for ballet and dealing with family problems, and then finally understand that he needs to do it just to prove himself that he was born to do this, and then fall in love with the old guy's granddaughter while she struggles to find a job while she's coming from a rich family.
It's blah-blah-blah. You need to watch only the first few episodes and you can guess how it's going to end.

Some might find it amazing, incredible and inspiring, but at the same time it's boring, long, nothing exciting and a plot we've seen many times before, just modernized a bit.
I was really hoping that I'll enjoy another good drama with him, but this was a little disappointing.
