Soft science fiction.
After the best theoretical physicist stroked the spacecraft a few times, the chemical composition was "undetectable".
Due to the extreme lack of scientific knowledge of screenwriters, the film had to go directly from the science knowledge of junior high school to the fantasy prediction of the future. Without the wonderful filling in the middle, it is really lacking as a science fiction film.
The final climax also lacks a fulfilling transition. Although in order not to appear abrupt, the front used a lot of flashbacks to slowly crochet the bedding. But not enough to make people feel.
This film is an idea, and all the characters in the plot are to express this idea, so they can only be superficial, losing the ego color and connotation that can move people's hearts. But the idea itself is not amazing, but relying on the climax accumulation of ducks and the incompetence of others to achieve the effect of moving and awesome.
I'm not happy to be fooled so easily, so, two points.
