Started off well but became too clumsy in the second half.

They really overplayed the intensity of some dramatic scenes. It's hard to explain but it's like they tried to portray some events happening to the characters as PTSD-inducing, or just really affecting them in a major way, but… they weren't all that intense to begin with. Made them miserable but it's just blown out of proportion, and it happens more than once. Just took me out of the story.

Choi Soo-young did a great job, but it's the child actress who was astounding. The fact that this thing works overall and has any weight (emotional or otherwise) whatsoever fully rests upon her shoulders.
