Rewatched

Even better the second time around, as I didn't have to experience the angst of not knowing what was going to happen next. I could fully enjoy the expressions, especially Yoon Ji Hoo's glares at those who dared to hurt Geum Jan Di.  I've read that Lee Min Ho cringes at his acting of Goo Joon Pyo, but I enjoy his raw, inexperienced state; it fits the character.  On a second viewing, I appreciated the character of Song Woo Bin more and wish he'd been more fully incorporated into the story. Of the F4 boys, he is the only one who wasn't given a growth arc or direction.

For fluff, MSR fits the bill. A second viewing isn't as enjoyable, because there isn't much to the drama that wasn't caught the first time around. I did enjoy the song "Same" that played throughout. 

Still fun the second time around. The first meeting of the two leads is just as enjoyable in review.
