The film presents an intriguing concept, features a protagonist who's easy to root for, and delivers some genuinely amusing scenes. However, it can be challenging to become fully invested in the story because the plot frequently loops back on itself to explore various possibilities; similar to chronic mental health struggles, it doesn’t provide a sense of complete closure. Tyler experiences a psychological condition that causes him to intensely visualize unfavorable results before events unfold. Consequently, he finds himself withdrawn and struggling to manage everyday situations. He's in therapy attempting to improve his ability to function. Given his attraction to Shane, who lives nearby and enjoys jogging, his therapist suggests he deliberately attempt to get acquainted with him.
