Never Let Go starts with an intriguing premise: a mother in a post-apocalyptic world fights to protect her children from bloodthirsty creatures by keeping them tied to a rope. If they let go, they're attacked. However, despite this interesting concept, the movie fails to create the tense atmosphere the story demands. Instead of pulling us into a truly dangerous and desperate situation, the film loses focus and struggles to convey the real threat the characters face.
The plot twists are another weak point. Some are too predictable, and from early on, I felt like I could guess where the story was heading. Though I'm not entirely sure, because the ending is especially confusing and poorly explained, leaving us without a clear conclusion - as if the writer wasn't sure what message they wanted to convey.
Director Alexandre Aja has proven capable of crafting good films with simpler themes, like the remake of The Hills Have Eyes, High Tension, or Piranha 3D, but whenever he tackles more complex narratives, such as in Horns, he tends to fall short. In his case, "less is more" really applies.
That said, I have to admit the different approach might attract viewers looking for something unusual. However, for me, this film didn't hit the mark. There was a moment of real tension involving the fate of an animal that made me anxious, but aside from that, I felt indifferent in about 80% of the situations.
It's far from terrible due to the original concept that sets it apart from other films in this subgenre, but it lacks the essential ingredients to truly stand out or leave a lasting impression.
