I really enjoyed M3GAN. A grounded and expertly eerie thriller that used its scifi premise rather than getting lost in it.
I'm half way through M3GAN 2.0, and I'm a bit disappointed. The plot leans heavily into magical AI tropes, and action movie cliches, and the half-time exposition dump took me right out of the story. Particularly because of the 'motherboard locked in a box gets smarter over time' nonsense.
If I saw it at the cinema, I'd be tempted to walk.
