It's amazing to see how Luc Besson has gone from talented amateur to essential visionary to ramshackle hack. The first half is a handful of lengthy sequences photographed with no enthusiasm - he used to be so daring with his camera placement - intercut with Morgan Freeman lecturing, shots of human primates and a criminal amount of stock footage. What's disappointing here is the unusual mixture doesn't feed any artistic hunger. It's just a frustrating structural mess, taking the worst aspect of a film like this, the pseudo-psychobabble, and extending it so that Lucy's transformation must wait for each of these scenes to complete. Those of you who had problems with the "10% of our brain" thing, that's only the tip of the script's fairytale philosophy.
Scarlett Johansson hits a lot of the same notes that she does in Under the Skin. Who knew that the curious study of humanity was such a natural fit for her? Apologies for the obscure reference, but with its fits of hysterics and bizarre leaps into increased levels of crazy, Lucy is like Under the Skin produced by Besson and directed by Andrzej Zulawski if he were given the budget for car crashes and fight scenes like this...
Unfortunately, even these bizarre pleasures are fleeting. The finale is wholly unsatisfying. Besson takes his idea too far, going from a nonsensical drug trip to an abrupt ending instead of having any payoff for the story or the characters.
