Lucy (2014)

 

A woman, accidentally caught in a dark deal, turns the tables on her captors and transforms into a merciless warrior evolved beyond human logic.

Luc Besson typically mashes up pseudo-science and action in this wildly lively sci-fi thriller  and ignores any narrative pot-holes and logic along the way; however, Scarlett Johansson is charming in th title role and ensures that the movie is quite entertaining.
