It is a great film ,I think the main point of this film is to make us think the relationship between nature and us. Can we really live without any green trees or glass? I think the answer is no, if we broke the nature balance just like they do in the film, the nature will revenge. The jelly fish which appeared at the end of the film is a symbol of the revenge of nature. I think it’s hard to say the ending is sad or happy , the jelly fish destroyed the city, but they brought some people inside them. It think it means that nature still want to give a chance to human.
