To begin with, the Russian title of this cartoon does not reflect the essence at all. And that is why, after viewing, there is a negative impression.
The theme of the underwater world has repeatedly been raised in cartoons and therefore it is very difficult to come up with something new. There is nothing new to come up with. “little man (fish)” saves his relatives. Of course, the children the story that the love of loved ones and friends gives strength, no matter what size you are, it is good. And environmental issues, which are a little, but still raised in this picture, are also important and great. But, first of all, as for children, I want to note that my child reacted with quite a lot of fright to the onset of crabs - they are painted really sinister.
Speaking of how it's drawn. Drawn well, but, in truth, this picture is very much inferior to cartoons such as "Nemo" or "underwater bratva", which is also about the underwater world.
I was also surprised by the way people are portrayed in this movie. I am very disappointed that when I look at them, it seems that all people are bastards. They're rare. Surprisingly negative characters that are really unpleasant to watch. But not all people are like that.
As for the plot, then, throwing aside the madness with a robot inside which there is a shark, let’s face it, I did not like it either. There was a feeling that the cartoon does not have a certain line of development. Heroes are going somewhere, someone is watching someone. And very often, during the viewing, the question “why?” popped up in my head.
