The elephant in the room: Is it a metaphor for the refugee crisis?

Hello there.

First of all, i have not seen the movie, and i do not have any particular view on the immigration crisis of Europe as i do not live there.

However, i have heard that many people have said that this movie has lots of parallels with the german refugee crisis and its very critical about it. In your honest opinion, did you feel that this could be applied as such?

I know its just a animated movie, but i am actually curious if the parallels was so strong that people could not help to notice it or its just someone cooking on nails here?
