From the moment M3GAN is fully constructed, it doesn't take too long for things to go from zero to creepy. We see that, following a conversation with Cady, Gemma is driven to improve the prototype robot she'd previously shown her boss. Cady, upon seeing an old robot of Gemma's named Bruce, notes that if she had something like it she'd likely never need another toy. This results in Gemma giving her invention a complete top-to-bottom overhaul, designed to be just right for Cady and potentially other children. This eventually results in the fully finished M3GAN, complete with fashionable clothes and a cute — if uncanny — face.
Upon their admittedly very bizarre introduction to each other, Megan quickly pairs with Cady as her primary user. It's during this sequence we are given a taste of M3GAN's POV, a recurring motif throughout the film. In an instant, M3GAN makes Cady's happiness her number one goal. Certainly nothing unsettling about that ... right? It's a moment that's disturbing due to the film's premise, meaning that you, the viewer, know already that this can only end badly. It's also another potential homage to another killer robot movie, in this case "The Terminator," particularly with the distorted cybernetic POV shots.
