A fun action movie (black comedy) about the time loop and with constant allusions to video games.
The whole life of the hero somehow (at first he does not understand a damn thing) turned into a game. He woke up because they were trying to kill him. When he was killed, he woke up in the same situation. Now it has an endless Game Over and attempts to end the day. Remembering everything that happens (where, as well as at whose hands he dies), the hero turns into a typical player in a computer game. The character is not on the screen, but the character. And he wants to survive as long as possible. And what's great is he does it with humor.
Those of you who have played video games know what it's about: you go through the difficult parts of the game many times, and when you succeed, that part stops being difficult, and the game turns into this "speedrun" — speed pass, when you start doing everything almost automatically. The film is a visual illustration of that feeling.
Just don’t think that the plot is an endless repetition of the same thing. Our hero constantly changes tactics, first by the method of pumpkin, and then finds leads. If it were a game, it would be an open-world, non-linear game.
As for meaning. In the intervals between the attacks, the hero tries to have time: 1) to figure out what is going on here, 2) why his wife was killed, and 3) to establish relations with his son-schooler, for whom he was not the best father in the world.
