Fairly rare one of a kind film. A high concept film that actually stays true to its core idea yet without losing viewer interest. Some irony here. While the film never becomes completely predictable, even to a jaded reviewer like this one, its process of de-constructing human relationship (brilliant, and better than all Woody Allen's films combined) generates the sequential "connections" with the viewer (ie, experiences that every viewer can relate to) which in turn keep the empathy going long after the initial sci fi "wow" is gone. Watching this (as an aside) you have to wonder if Scarlett Johansson's career can get any more interesting? In the Marvel films she plays an uber-woman, In LUCY she a woman who evolves beyond evolution itself. And here yet again she plays an OS that transcends reality. Makes for a nice resume. Notice how Amy Adams plays every scene with no makeup? Talk about a director making every effort to keep an actor's natural beauty from hijacking the film...?
