Sadly incoherent

Rating: 3/10 (19 March 2015)

Watchable because Johansson is charming and the production values are great, but it seemed like writer/director Besson took stupid pills to achieve the mood he wanted for this movie.
Not only is the biology absurd, but the physics are ridiculous (this is part of the premise) and computers/communications simply don't work that way. At one point Lucy draws on the window of a car to use mental powers. WTF? Even the English is a bit off, making supposedly well-educated genius characters sound ignorant and confused.
Lucy seems to have a plan for humanity, but she doesn't even bother calling off the cops before killing a bunch of them; yet she doesn't kill her helpless enemy, making trouble for herself and everybody else.
I expect better from Besson.
