First, this is not a science fiction movie, it belongs to the category of fantasy movies. Second, don't read the astronomical science content from the film, because there are only a lot of philosophical and political elements in the irony. Third, although the film worked very well according to the technology at the time, the plot was slow and slow, and it seemed like a waste of time.
In fact, none of the above is important. The key is that such a film that the director said is that everyone can't understand it can make a group of people who can't understand it say that this movie is great. I feel that only religious worship can do it. Bar! ! !
