The first part was a real detective story with an investigation and a puzzle.

This part begins as an entertaining youth movie. The mystery box looks fantastic and therefore out of place in this movie. The story itself is not as complicated as it was presented.

There are also contradictions. Why is Miles so rich and powerful if he's a loser? Why did his "friends" immediately abandon him when his house burned down? How did it affect? Why is the house exploding everywhere, as if the fuel is everywhere in it? If this fantastic fuel generates energy, then it's not in the house anyway. The house is powered by electricity.

In general, the story is a detective story, but it is spoiled by inappropriate fantastic elements: a box with a mystery

and a burnt Mona Lisa painting.
