Variety praised the film for creating a "Christopher Nolan–esque, fantasy-tinged narrative puzzle" without the need for a major studio budget or elaborate CGI effects. He also noted that while the narrative complexity is engaging and well-crafted, some viewers may feel that style outweighs substance, and that the characters "have so little context or inner life that they might as well be named Protagonist, Mystery Obsession Girl, Sidekicks 1 & 2, Obligatory Girlfriend, and Mom". Harvey further highlighted Dylan O'Brien's empathetic performance and the film's strong visual and musical presentation.
Glenn Kenny of
RogerEbert.com emphasized the ambitious themes of the film, which explores the nature of time, fate, and existence itself, but criticized the main character, saying he is "mopey and uninteresting from frame one" and that some of MacBride's narrative attempts "just don't quite work". Nevertheless, Kenny acknowledged that the film cannot be denied credit for its ambition in exploring complex temporal structures. ==References==
