Certainly not dull... but has some big problems

Rating: Null/10 (1 February 2015)

Even without using the drug that increases the brain power of the movie's title character, one can quickly figure out why the movie was a big box office success. The idea of one's brain power increasing greatly is an intriguing one. And writer/director Luc Besson does keep the movie fast-paced, with plenty of action and special effects along the way.
Despite this, I think Besson should have worked on the script some more, because there are some major problems with it. The earliest and most glaring problem is the character of Lucy herself. We know nothing about her when she finds herself in trouble, and we learn little about her for the rest of the movie. Also, she is kind of a cold and heartless character once the drug starts to kick in; among other things, she hurts (or kills) innocent people along the way. And there are some glaring flaws with her actions, like why she doesn't kill the chief bad guy when she gets the chance to halfway through the movie, as well as why in the climax she doesn't take care of the bad guys BEFORE subjecting herself to the actions of the scientists. And the abrupt end will have most people in the audience saying, "That's IT?!?"
The movie is not without merit, but in the end it shapes itself to be a brainless treatment of a cerebral subject. I realize that there are some people in some situations who might find the movie a breezy way to pass the time... but if you are smart enough to know you are smart, I would strongly suggest you find another movie. Action movies made by the right hands can be smart, but this one simply is lacking brains.
