Paradox: the picture is removed indoors precisely in order for the endless space to come to life on the screen. However, for two astronauts, he acquires a specific meaning, because they are closed, as in a tight box, in their spacesuits, and then in the premises of broken, deserted and doomed to destruction spacecraft. There are three of them in the film: American, Russian and Chinese. The crew leaves each, each is not like a house, but like a coffin, each generates a feeling of terrible claustrophobia.
This turns the "production novel" about professionals working in space, or a disaster film into a philosophical essay about the modern world in which man has no place. The film could have been called otherwise - "Weightlessness". It is in this state that the heroes constantly reside, and it is difficult not to consider the metaphor here.
"2001: A Space Odyssey" the great predecessor of "Gravity" (some of the scenes here are candid quotes from there), told about the conquest of space. Man turned out to be more powerful and powerful than a powerful computer, and was able to challenge the extraterrestrial intelligence.
The validity of the humanism Stanley Kubrick has expired completely. Now people are completely dependent on faulty equipment and hopelessly read the instructions, wondering which button to press. They no longer seek space: their only dream is to escape from there.
The inhuman beauty of hopeless and silent space is not for them, and finally they realized it. A voiceover flashes the memory of what the Earth has become; is this the place to really go back? However, there is no other way out - and, by all appearances, there will also be nowhere to run from Earth.

For me, "Gravity" - a spectacular, fascinating, absolutely not highbrow spectacle, demonstrating the latest achievements of cinematic technology, but at the same time flawlessly accurate portrait of a modern man, isolated from their own kind and lost in space.
