The movie's premise was quite good. The siblings hide in a temporal B&B to avoid the law. However, they soon discover that leaving is not as easy as they thought. They can communicate with the people responsible for time travel using a tape recorder locked in a safe. They are tasked with confronting an adversary who appears later in the story.
The execution, however, leaves much to be desired. I agree with other reviewers: the cinematography is excellent, the sound and music are above average, and the acting ranges from superb (the brother) to good but somewhat forced (the sister). The main drawback of the movie is its screenplay. While it has potential, there are super boring parts interspersed with a few sudden twists. Moreover, many elements are either left unexplained or explained in a lacklustre manner.
Despite its shortcomings, I enjoyed the movie. It would have benefitted from being 30 minutes shorter, featuring more realistic sibling dialogues, and providing better explanations for a few key elements, for example, delving deeper into the adversary's identity. Still, it was more than satisfactory for a low-budget flick.
P. S.
A few other movies gave me similar vibes, most notably Timecrimes (2007), The Field (2019), and The Endless (2017).
