The child actors amazed me with their acting!!! Worth watching the whole thing just for them. The main actors did amazing and the storyline isn't dragged on. I don't know why I havens watched this show before.

I was avoiding any dramas with more that 16 episodes and this one was said to be 32. When I started watching it I realized the each episode is around 30 minutes :)

To be honest, I wasn't really satisfied with the explanations of the brothers case in the end. It was to vague for me.
