Hearing about it winning all sorts of awards, I thought this would be sure-win. Turns out, it's yet another K-drama that fell into the same holes as so many others when A-listers are cast in the film.

What I liked:
- the child actors and their character development
- the mystery behind the adult characters
- watching the characters try to survive as ordinary citizens in spite of their superpowers.

Loved, loved, loved Lee Jong Ha's acting.

What made me drop this show:
- the excessive "telling" instead of "showing"
- the excessive flashbacks - not every single little subplot from the past deserves 30+ mins. of a flashback
- disappearing the teenaged characters halfway through the drama
- switching to focus way too much on the adult characters
- too much about a government conspiracy that makes it become just like any other K-drama about Korean gov't conspiracies.

Soundtrack was negligible.
