Luc Besson's "Lucy" is Batman Diogenes, wandering through the world seeking truth, knowledge and fighting for justice. Unlike her male counterparts, she is unencumbered by the heavy load of testosterone. She is able to see more clearly. She doesn't get side tracked by the blandishments of sex or power. She is on an evolutionary mission.
It doesn't diminish her quest that it occurs by accident. The victim and beneficiary of a drug deal gone wrong, Lucy is subjected to a drug dose which expands her mental capacities. She takes us on the stages of this journey even as she fights to protect herself and others from the evil cartel.
