Wow.... spoiler alerts.... i thought it's a robot AI movie (though George was really a robotics engineer) but it's really about that other technology. i think some of the plot went in on ahead too far, but in the end it gives weight to how or what someone would do or buy some technology just to spend again with a loved one who already passed away. and my heart sank for J2, a robot who also fell in love with her supposed creator.... hu hu hu poor thing. it was a different story caught or developed inside a "dream story". goes to show how charming the protagonist is whether in real world or in dream world, it was like parallel worlds... consistency yes... good job script writers and cinematographers...
