If you look at M3GAN, the new dancing uncanny valley murder doll movie from Blumhouse, writers Akela Cooper and James Wan (the duo behind Malignant), and director Gerard Johnston (Housebound), and think, “Hell yeah,” you’ll probably have a fine time. What’s fun about it is really damn fun, equal parts campy, goofy, and spooky. In these moments, it knows precisely what movie it is, what the audience wants, and how to deliver exactly that. It's everything in between these fun bits, however, where the problems lie.
