I just got through my second watch of this, and after watching probably 300 C-/K-/J-/T-dramas, I have to say that the acting in this show is some of the best, in my opinion. Not everyone was perfect in every scene, but I didn't question the actors' reactions any more than I would have questioned the reactions of people in real life. And although there are a few plot holes, I personally have enough imagination to fill in the blanks.

The kids totally stole my heart in every scene they were in, and made the entire drama worth watching. While their delivery sometimes lacked emotion, anyone who's been around young kids knows that's often the way kids speak, so it was believable. And their crying scenes were on point, especially when the boy was chasing after the taxi. I hope he got an award for that scene alone.

My original rating was an 8.5, but I bumped it to a 9.5 this time around. Of all the shows that I've watched, it's rare that I WANT to watch a drama more than once, and even rarer that I actually DO it. But this show is definitely worth it.
