Overall, Lucy is pretty interesting

Rating: 8/10 (25 August 2016)

Lucy (Scarlett Johansson) starts out as a young nobody who, through no fault of her own, gets caught up with a Korean drug gang. The drug lord decides to use her as a drug mule, and has a plastic packet full of CPH4 embedded under her stomach. Through recklessness by her drug handlers, the packet rips, leaking the CPH4 into her. The CPH4 gradually opens her brain, and she gains knowledge far beyond any human. She is able to see and do fascinating things, but she also gradually loses what makes her human. She has no interest in striking back at the drug gang, as her intelligence has progressed beyond this world. Lucy calls her mother, but her basic message was: "I love you mom, but I'm going someplace that you couldn't possibly understand, and I can't come back. Goodbye."
Lucy consults Brain Theory expert Professor Norman (Morgan Freeman) on what she should do with all of her knowledge. He suggested that she pass on her knowledge to others, although he was also wondering if mankind could handle such knowledge. The drug lord, of course, is determined to kill her.
By the time Lucy reaches 100% of brain capacity, she ceases to exist as a physical being.
Lucy starts off as a pretty good story, but there are a couple of flaws later on. The big car chase scene, involving multiple car crashes, was pointless. Lucy could have just used her brain to make the other cars stop, and mentally just pushed them aside. Same thing for the big shootout scene at the end. Lucy could have just made all the bad guys collapse. Those scenes were just put in as action filler, but they kind of subtracted from the story.
