A city is built underground with a box set to open in 200 years. Now with natural curiosity, two young girls and a boy attempt to seek the above world when the city with no natural light begins to have black outs. Why have LCD and HD TVs when your TV is so synced into the room that the power goes off right at an important moment. I didn't finish the movie then, because the power didn't come back on for a while, but I watched the rest of it last night. It was fantastic, definitely a family movie. I rated it a 4.
