What happens when you combine the premise of people committing suicide from The Happening and an entity attacking us based on our senses a la A Quiet Place? Bird Box? Yeah this movie combines both concepts and it is not a ripoff but rather a unique baby that isn't perfect but quite intense with zero jumps scares and less corniness. The scene where our society breaks out of order in the beginning is intense as hell and the part where the entity possesses these individuals is scary and lacks the corniness of The Happening, where the individuals there commits suicide in quite a funny or cornier way. Even the part where the survivors have to survive on their own during the flashback scenes is intense as hell. The only part where the movie feels less intense and gives me a mixed feeling is during the current scenes in the first-second acts in the movie. Whenever the movie does that it felt less intense and no doubt the slow and suspense is there, it felt a bit off and when the third act comes in, it creates an uneven tone but nevertheless I was still invested in the story. Overall, I highly recommend this movie if you are into this post-apocalyptic kind of movies as I find it a worthy entry in the genre and if you liked A Quiet Place or dislike it for its jump scares or lack of gore, you might enjoy this more. For sure it is way more serious than The Happening (Thats unintentionally funny. I wanna see that again for sure).
