The first 20 minutes of the Significant Other movie can be slow. You might wonder where the story is going. Nothing really happens apart from a couple misfiring as they try to communicate. It is after this lazy storytelling upfront that the movie picks up some real momentum. You have to be patient. You have to catch the small clues, especially the change in the facial expressions of the couple, to spot exactly when the story shifts in a different dimension altogether. While the first few minutes might make you wonder about a couple aimlessly drifting around in a spookingly empty forest, the last few minutes of Significant Other quietly explain why - something so remote and isolated was critical for the aliens to give shape to their sinister plans.
The middle part of the movie does well. The director of Significant Other does not try to explain too much. You cannot be an alien movie concept novice these days, considering the amount of alien-focused content that has been streamed across global OTT platforms. The middle part of the movie Significant Other is tense. There is very little violence and practically no body horror. A few bodies get slit down the middle, but without the usual gore and unwanted special effects. The middle part of Significant Other is what gets it through as being a very watchable movie.
Calling Significant Other a suspense mystery with a slight sprinkling of the alien invasion flavor is perhaps the best way to describe the movie. You will love the intensely green wilderness cinematography that makes a significant contribution to the movie until the story starts twisting. I could not spot anything that could be marked for gore, graphic violence, or language.
