I really liked the first half of the cartoon. Despite the fact that it is full of cliches and platitudes, it turned out to be fun, with its atmosphere and intrigue.
The second half of the film is much weaker due to the undeveloped world. The wholeness of the picture is lost, you cease to understand the rules of the game.
Also indistinct, unconvincing is the idea and argumentation of the characters for a particular action. For example, I didn’t understand why Sam didn’t want to insert 2 green stones, because it would be good for all parties. Her argument seems far-fetched.
As a moral, they tried to suggest that “even in failure you can find advantages.” This is not the worst option, failures happen and you need to learn how to cope with them. But it is presented clumsy and in conflict with the world of history.
In general, the cartoon is not without drawbacks, but it is quite possible to watch with children.
P. S.
The joke with the sandwich on the wall at the beginning, though quite beaten, but how accurate, label and revealing. It's my case, 10/10.
