If this was "just" a love story then it would be good. Writer/director Akash Sherman portrays two broken people well and both the main actors are up to the task, so this should be a slam dunk, but it isn't.
The science isn't quite right, but it's mostly like Hollywood movies i.e. it has a central premise that is slightly exaggerated and then spins that way too far. For me that part, while not great, is still bearable. The part that makes it pretty intolerable stems from films use of god. It starts well enough: he has a scientist who does not believe in a god and we learn his motivation and his counterpart who has very good reasons to believe in god. It's when the film decides it knows the answers the it falls flat, not because the film takes a side, but because it does so in ridiculous ways. The last ten minutes are a travesty with one ludicrous thing after another. Before the last twist I was heading for 7 out of 10, but in the end 4/10 is generous.
