Not terrible, if you can get over the (lack of) science.

Rating: 5/10 (1 February 2020)

The main problem with this film is its classification as Science-Fiction, because the science aspect is laughably awful. The myth of humans only using 10% of our available brain power was debunked a long time ago (although I can understand why it persisted given the terrible decisions most of us make on a regular basis).
That said, the film does have some plus points - production values are high and the acting is generally good. The first half in particular contains some scenes which generate genuine tension - it's not hard to imagine oneself in a situation (like Lucy) where your fate is completely determined by others and your life is of little concern.
Unfortunately the second half of the film is something of a mess, with action and special effects taking the limelight rather than the story or dialogue. It would have been nice to find out a little more about Lucy and how she came to be in this situation.
Overall I'd say this film isn't terrible, but I think an opportunity was missed to create an interesting and compelling story. And the science aspect is cringe-worthy for any true Sci-Fi fans.
