This is a solid, inexpensive science fiction film with supernatural elements and a sense of cosmic dread, penned by Justin Benson and directed by him alongside Aaron Moorhead, who also play the lead roles. It evokes the feeling of an episode from *The X-Files*. At its core, the story follows two brothers (Benson and Moorhead) whose lives have been marked by hardship. As children, they briefly immersed themselves in a UFO cult lifestyle at Arcadia Camp, located in Southern California—a place where time behaves erratically and unusual events occur. As days turn into nights, increasingly bizarre occurrences begin to plague them. They eventually realize that the area is actually a small pocket dimension within a desert landscape, inhabited by warped pockets of spacetime and an unseen multidimensional being. Time repeatedly resets within this space (sometimes in truly awful ways), causing its inhabitants to die and then live again. That’s essentially what living hell feels like. This isn't immediately apparent; the unsettling nature of events gradually unfolds from the film's midpoint, reminiscent of other modestly-funded films with inventive concepts such as "Project Almanac" (2017), "Primer" (2004), and "Synchronic" (2019). The special effects, despite their limited budget, are surprisingly effective, and the largely inexperienced cast delivers performances that feel genuine. The film's visuals and music become particularly impactful starting around the middle point—featuring a synthesized score incorporating samples of “House of the Rising Sun,” depictions of three moons (a full third moon signifies being trapped), and other subtle circular shapes. With more polished writing, it could have been even better, but as it stands, it’s an inexpensive cult film (no intentional wordplay). I'd rate it a 7 out of 10 or a B grade. It doesn't present entirely new ideas, but the way they are presented feels fresh.
