The whole film is like an RPG game with short main missions but abundant side missions. But movies are not games. Movies develop along the time axis. The audience only expects to see a wonderful story, rather than seeing a bunch of big scenes, but in the end they don't know the point of the story.
It's best to split this film into four movies, each of which can make a good story.
The first part is about human beings immigrating to space for the first time. Political groups wrestle with each other, and even send killers to assassinate the pioneers of immigrants. At the end of the day, justice defeated evil and finally successfully emigrated. This is a suspenseful thrilling science fiction film full of conspiracy, fighting, suspense and psychological struggle. A similar movie is "Space Transport Cargo".
In the second part, a spacecraft accidentally encountered another spacecraft and went to investigate, but found that there was a spider-like alien creature. The spider attacked humans. In the end, everyone worked together to destroy the spiders, but found that the spiders had parasitized on people and eventually turned people into humans. Become a spiderman. This is a sci-fi movie of alien creatures full of horror and disgusting scenes. A similar movie is the "Alien" series.
The third part is an artificial intelligence robot. After living with the protagonist (of course, it must be a child) for a long time, it gradually becomes human. In the end, it fought desperately against evil forces to protect mankind, and sacrificed heroically after completing the task. This is a robot science fiction film full of fighting, humor, and moving scenes. A similar movie is "Terminator 2".
The fourth part is the main plot of the film. The father fell into the vortex of time to save his family and met his grown-up son. The two had misunderstandings and disputes, but in the end they both got mutual understanding. The son finally sent his father back to the original time, and everything returned to normal track. This is a time travel science fiction film full of affection and humanity. A similar movie is the "Back to the Future" series.
Well, basically this Lost In Space is so magically kneading the above four movies together.
