Don't listen to the negative reviews. Watch the movie & decide for yourself. The old saying "everyone's a critic" is truer than ever these days.
This movie presents an actual, realistic picture of how AI becoming sentient could play out. And in my book, the script was well written, acting superb.
I think people leaving negative reviews about this move are doing so because, deep down, they know this is where we're headed, and it scares the daylights out of them. It's being set up this way already. AI has been in the limelight on Wall St. for at least the last 3 years now. Realistic robots like Sophia already exist.
The moral of the movie IMO is simply to enjoy the life you have now, and treasure each moment with your loved ones. Because tomorrow you never know what might be different.
