I really enjoyed the movie and thought it was really well put together. The movie depicts how AI will interface with multiple generations and different needs. It shows how AI could potentially affect parenting, career, social dynamics, education, and healthcare, all within one family. It shows a balanced perspective of the benefits and obvious risks of allowing AI to control one's life. Not really a horror movie, just some jump scares thrown in to justify being horror when its really a thriller.
I can only guess most of these negative reviews are funded by AI companies/self driving car companies, because being aware of potential risks is not something they want people to think about.
