I liked the idea of an invisible entity in this film. Kind of done already in Shamalayans Happening but this time it doesn't kill - it turns you psycho with all the associated 28 days later type zombies that we have come to know, love and ultimately get bored with. The interesting thing is this entity obviously has an evil intelligence and so chooses to converts some people to its evil ends. I wasn't sold on the whole movie, I don't think it hung together as well the recent Last Boy which had a similar lethal entity but was done much better. And like most people I found the ending of Birdbox an utter disappointment.

6/10
