It just seemed slow, and extremely pointless. By the time he gets to Neptune, 1 1/2 hours of movie-time had gone by, and nothing worth anything had happened. Then there's 30 more minutes of pretty much nothing. Takes anti-climatic to a new level.
Real science fiction is this: It's an exploration of how humans will react to possible scientific innovations.
So, something like Blade Runner is science fiction. If we had artificial people, how would we treatment them? That's looking at what most humans would do if suddenly we had artificial workers, soldiers, prostitutes, and so forth.
Some people hate them, so don't, some find it okay to fall in love and just don't care. That is what would happen in real life with that kind of technology.
Hollywood typically doesn't make those. It makes fantasy science fiction, like Star Wars. More frequently it makes relationship movies in a SF settling. Star Wars again, but really almost all recent SF is a movie about a relationship with your dad, etc.
My only explanation is that jews run Hollywood and do most of the writing and so they belong to an insane cult, so they can't write SF because they believe in magic.
Anyway, this film is about abandonment dads. Lots of guys abandon children and the reason they do it is because they are on some useless quest. In the ghetto the guy wants to get all the bitches and have fancy clothes. The corporate guy wants to be some leader, get bitches, fancy stuff, and be CEO, and so on. That is what this movie is a metaphor for.
There really is nothing that important in life. If you get to be CEO you still may end up lonely and having failed at being a family man who creates love.
The dad in this had huge dreams he was sure of and his family meant nothing. His boy still loved him and came after him since he had no family to love since he never learned how to do that. He finds dad and dad is totally wasted from his big plans and is useless and dangerous. The boy returns home to create some love.
Nothing SF going on in the story at all. It could be set in any circumstance.
There are whole documentaries about how jews own Hollywood, made by them. It's THE TRUTH and if a fake religious cult is in charge of telling stories, guess what, the stories will be influenced by their insane culture and beliefs.
I was left thinking a bit in-between about it also, but overall I am thankful for it - something more sensible to add to the history of science fiction cinema.
To me it was like a cross between Solaris, 2001: A Space Odyssey and Interstellar.
