Tyler Lake’s review published on Letterboxd:
I couldn’t shake an uncomfortable feeling like I was watching something from an alternate universe, one where the emotional divide between humans and robots isn’t as cavernous as it is in our own. Even when M3GAN goes for laughs, the jokes are cold, almost like they’re meant for a robot audience. This only adds to an awkward feeling of inter-dimensional voyeurism.
I don’t think there are any performances to write home about. This isn’t that kind of film. It’s really just a patchwork of familiar themes and nods to Child’s Play, Terminator, Dolls, and many more. However, its real strength, in spite of the influences it wears on its sleeve, is an ability to make you squirm for reasons that aren’t easy to articulate.
