The film follows a formulated and well known plot line "somebody is wronged and something is taken" its all about getting the taken thing back. Nothing new here.
The AI element of the future robotic AI existence makes the AI so human like that they are just normal people and therfor nothing special either
Blah blah vlah boy gets the girl happy ending all round
An opportunity missed to really scare the pants off people with the true potential of AI on humanity
