Take time travel out of the scenario, though, and even the denser, more classically sci-fi first act of the film could still run under the same circular title. Young Joe's life moves in endless repetitions. As a hired gun employed by future mobsters looking to dispose of their enemies in the past (where bodies are harder to track, especially if they technically do not exist), Joe's life follows a set pattern. Be at the right place on-time, blast the target when it suddenly appears, collect his money and go party. Joe saves most of his money for the early retirement people in his line of work receive, but as Johnson's montage of Joe's routine speeds up under the influence of the cleaner's drug use and dispassion, it becomes evident that retirement may prove more debilitating for him than his profession. Not that he will get to find out, however, when his final target, himself, manages to overpower his younger self and threatens to create a whole new timeline. Imagine how weird this would be if the director didn't try so hard to avoid time talk.
