I enjoyed this for the most-part. The momentum in combination with the 90 minute runtime, kept myself entertained for the entirety. It's far from perfect, but it's entertaining. Then again I didn't labour over the science to over complicate the overall enjoyment. The climax is probably the most contentious and unfavourable issue, but I appreciate the intent of Luc Besson's vision.

Note: It's probably best to ignore the super low-scoring trolls, who create accounts to downvote and spread negativity. If you don't have some constructive criticism, don't say anything at all. Any 'Not helpful' downvotes on this review are probably by the aforementioned.

Lucy (Scarlett Johansson) is studying in Taiwan. Her new friend Richard tricks her into delivering a suitcase. It's filled with a new synthetic drug CPH4. She is kidnapped by kingpin Mr. Jang and forced to be a drug mule surgically inserted into her abdomen. She is kicked by her abductor and the drug seeps into her system. Professor Norman (Morgan Freeman) has a theory about the human mind. Most use only 10%. The drug opens up Lucy's mind turning her into a superhuman as she uses more and more of her brain. With the help of Paris police detective Pierre Del Rio, she tracks down the drug from the other mules and contact Norman to transcend her humanity.

This starts off as a fun action thriller filled with inventive Luc Besson touches. Johansson is good transitioning from victim to machine-like superbeing. I like going to a lesser used exotic location like Taiwan. However Besson tries to be profound. It descends into a lot of mumbo jumbo. At which point, I realize the whole movie is a lot of scientific mumbo jumbo. It wouldn't matter so much but Besson seems to really want to say something. He ends up saying nothing.

I agree with a couple of previous reviewers. To maintain real interest, we really need some conflict. I don't mean a bunch of Korean guys chasing after you. It has to be a problem the protagonist has to solve or at least deal with. Lucy unfortunately helps a friend and ends up in really deep stuff. She is used as a drug mule for a crazy drug that can up human intelligence. She was never intended to use but a guy assault her and breaks the bag inside her. She immediately begins to divide cells and transform into a new creature. The second criticism is a lack of explanation as to why she loses all compassion and empathy. She does have the revenge thing going but she is almost zombie like in her interactions with others. Is the point that we are just animals with reproductive and survival instincts? Other than teaching his classes and giving us a reference point, Morgan Freeman is of no use. He just stands around saying he doesn't know anything. Lucy eventually takes us on a ride through time but why. Is she just absorbing information. If so, what is she going to do with it. The long and short is that it is disjointed and relatively pointless.
