As I watched this scifi adventure I was only giving it a 6 because of inconsistancies, I kinda like my science fiction to make a little since. But I upped my rating because I was on the edge of my seat and rooting for these kids to survive. I thought the acting was pretty darn good. And I especially liked that this J drama did not have the cartoon feel that I see so often in Japanese drama. The story is just so so because it is super preachy and I don't like preachy. The romance was sweet. Loved the crazzy theme song. lol
