Terrifying, plausible, cliff-hanger

Rating: 9/10 (8 July 2018)

Watching the movie leaves the viewer feeling frustrated and claustrophobic, just like the concept itself. The premise is that there exists a way to send someone back in time to avert disaster, but there are little time and grave consequences for doing so. A great combination of sci-fi and thriller with solid acting and good pacing. As others have noted, this movie is a fresh concept, and I wondered why we don't see more of the same.
