The film is based on a book by Stephen King, but it's not a horror movie or a thriller. It's a perfectly good film about the meaning of life, one that makes you think about big, universal things: time, a person's place in the universe, and their seeming insignificance compared to its scale. Because of that, the film periodically carries an atmosphere of hopelessness and the feeling that some things just can't be changed.
The central part of the film is taken up by dialogue, which might make it seem a little boring, especially given its considerable runtime.
It uses a pretty clever trick: in the first part, the viewer is already made to understand that the ending will be sad. Thanks to this, the second and third parts make you empathize with the main character even more. The film also has a few interesting allegories. For example, the idea that the death of one person is equivalent to the death of an entire universe. And that's completely understandable. First, for someone, the loss of a loved one truly does feel like the end of their own world. Second, if you draw an analogy between the human brain and the universe, neurons and their connections are somewhat reminiscent of stars that are born, flare up, and die, just as the human brain itself eventually perishes over time. The allegory of the sealed attic seems to hint that sometimes it's better not to know your future, but to live quietly and enjoy the present. King also didn't overlook mathematics — one of the most important sciences, with which you can describe both the laws of the universe and the most ordinary everyday processes.
Even though this film didn't give me any kind of "wow" feeling, I still liked it. It raises global themes of time, the meaning of life, and death, and after watching it, it leaves that distinct aftertaste where you want to keep thinking about what you've seen for a long time and discuss it with others.
