If only you can watch it for Scarlett alone.

Rating: 4/10 (3 September 2014)

'Humans only make 10% use of their brain and what if there is a drug which can trigger it to 100% usage in just a few hours?' - That's the basic thought behind this science fiction cum action thriller cum philosophical film incorporating many vague metaphors at times conveying nothing.
Revealing its basic plot, LUCY is about a beautiful girl, who unintentionally gets caught in the international mafia trap and is given an unsafe drug which in turn enhances her body function drastically. The drug starts increasing her brain power in an unusual manner and she soon explores some exceptional super-powers much beyond the known capabilities of a normal human being, which in turn help her to break through the mysterious nexus of underworld, drug mafia, police and more. Her brain usage keeps on increasing as the film progresses further and it all ends when she eventually reaches to the maximum level of 100%.
Now the short synopsis shared above sure sounds pretty interesting but I wish the film was equally engaging too justifying its novel concept. It has a promising start featuring a betraying friend and the Chinese don but soon starts giving away due to a weak script and too much focus kept on its style and presentation. The film actually doesn't work because of its thin storyline stretched for long and an unconvincing narration, despite having some excellent production values and superb graphics.
With an otherwise fine performance by Scarlett Johansson, who later fails to leave an impact due to the ineffective culmination of a great plot, LUCY also wastes Morgan Freeman as the professor/researcher working on the brain concept. The film doesn't explode later as per the expectations raised in the first ten minutes and hence can easily be rated as a flat science fiction which keeps on giving some forced philosophical lessons at regular intervals in vain. In fact LIMITLESS (2011) made on a similar concept was a far better entertainer comparatively.
In short, LUCY's brain might have reached its 100% in the script, but the film couldn't even reach 50% in terms of satisfaction offered, honestly. So you can opt for it only in case you don't mind watching Scarlett alone for those 90 minutes.
