There is no excuse for basing a screenplay on taking seriously a well known urban myth and writing it as if the audience believes the myth. Did no one up the entire production line step out and call bullshit on the discredited 'we only use 10% of our brain,' idea? I am so embarrassed by seeing actors I admire, Scarlett Johansson and Morgan Freeman, deliver solid performances on the basis of an idea at which most people laugh.

I've also struggled to appreciate several o Luc Besson's movies but this is is by far the worst one. A lot of jibber-jabber bullshit with sexy Scarlett Johansson, lots of FX, predictable ending in Paris and a pointless car race on its streets. Better spend your time on something else ...

Ignorance brings chaos, not knowledge. Lucy is one of those films that brings about furious reactions, it is after all a science fiction type action thriller. They always divide film fans right from the off. It's a film that to all intents and purposes needs to be viewed just as a cinematic experience, as a piece of popcorn fodder that may try to be something more cerebral, but ultimately is a daft - but hugely fun - piece of film. Luc Besson writes and directs a film that sees Scarlett Johansson duped into being a drug mule, with the transportation of drugs sewn into her abdomen. It's a new drug, boy is it a new drug, and when things go belly up and the drugs are unleashed into Scarlett's system, she's a threat - or hope - to mankind. It can be, and has been, called pretentious et al, such is the science factor, which is perfectly understandable, so any hope of tight science fiction musings will only end up in a crushing disappointment. Undeniably Besson and his backers thought they had something to say, to open up the film watchers' minds to something deep and probable, to be relevant and viable. But unlike the makers we the viewers didn't have access to donepezil, so we sadly couldn't all turn into Bradley Cooper and be limitless in our viewing capabilities. Personally, it's a rollicking fun film for two thirds, when it's about Scarlett kicking butt, a revenge driven babe, it grips and shakes all the genre compliant cinematic senses. The ending, the grand finale, infuriated me, and by the looks of Morgan Freeman (coasting for easy money), he was also a little frustrated. But I had fun, yet on the flip side if anyone fronted me up and said they hated the film with a passion? Then I would understand and take them home to play with my chemistry set. 7/10
