This film has two writers, and you can certainly tell! It's almost as if the direction of the film is caught in a tug of war with Max Landis pulling it towards horror/monster flick and Roseanne Liang pulling it towards a feminist war feature. Both would work and make compelling viewing, but together it leaves you scratching your head. Personally I came into the movie expecting a monster flick, which it partially was, until it becomes very obvious that Max Landis was taken off the project causing the film to suddenly change it's tone. This new direction feels out of place and jarring, simply due to the first chunk of the film being set up for an entirely different ride. In the end it's unfair to both stories as neither idea is fully fleshed out or realised. This being said, Chloë Grace Moretz gives it her all and puts in a strong performance, bringing some entertainment and weight to this film, even after it's confusion as to what it wants to be. 3 stars, but all of them are for Chloë.
