I loved M3GAN, it was funny and creepy, the main point, like you said, it's not about the doll itself, it's more about parents giving devices to children so they can have free time from parenting, and it's horrible, but if you're not gonna spend time with your children and let a screen raise them, well, then don't have any children.
And honestly, I heard a lot about her dance, and I was expecting like a few minutes dance, but no, it was a 5 seconds dance, that's the only thing that disappointed me.
