Well, this will save me the hassle of recapping; watch this:
In case you didn't watch it, ScarJo is the titular (this means title character; not a comment on her boobs) character, a party girl in Taipei, Taiwan whose current hookup entraps her into delivering a briefcase containing drugs, gets drugs sewn into her, they leak, she becomes a cross being Neo and Dr. Manhattan, hijinks ensue. That's pretty much it.
Writer-director Luc Besson has always had a thing for kickass chicks from his original La Femme Nikita - which spawned two remakes, the American Point of No Return (pretty good with a better 3rd act) and Hong Kong Black Cat (not very good); and two TV series, La Femme Nikita (bought the 1st season on DVD and gave up after 2-3 episodes) and the recently concluded Nikita which I quite enjoyed - and The Fifth Element with Milla Jovovich's Leeloo. Thanks to ScarJo's (she hates being called that, don't you ScarJo?) performance which starts off suitably terrified and ends up approaching god-like power (more on this in a moment), Lucy is another cool Besson creation.
While the movie moves swiftly and efficiently, there really isn't much more to the plot than what the trailer shows, there are so MASSIVE plot holes beginning with the whole drug mule concept (if it looks like blue laundry crystals, why not ship it in small detergent bottles that travelers would carry?) and why someone carrying valuable cargo for a brutal crime lord would be beaten up in the first place? I don't think we're supposed to think to hard about the details, but Besson used to be better with these things. (See Léon, aka The Professional, which was Natalie Portman's debut, for a good example.) At the end, after Lucy has amply exhibited superpowers, when the crime boss says, "I'll kill her myself," I leaned over to my girlfriend and whispered, "Based on what that has just happened makes him think he's going to be able to do that?" Indeed.
On one level, Lucy manages to answer the question of what happens when people get unlimited knowledge and power through technology much better than the stupid and woeful Transcendence did, but I wish Besson had scribbled more than his usual notes-on-a-cocktail-napkin I imagine he does for the projects he has others direct like From Paris With Love and the Transporter series. It felt like another reel of exposition could've easily been added to more gradually track her evolution as a superbeing at the cost of her humanity. There's a touching scene where she calls her mother under crazy circumstances and another where she announces that she's losing her old self, but it would've been interesting if there'd been something showing an in-between state as her emotions try to hang on while her intellect tosses them aside.
I've been seeing some weird things in the reviews and coverage of Lucy. Some hack at Forbes, in reporting that it's the #1 movies this weekend, rages repeatedly about how the marketing is "full of lies" and "blatantly misleading" - read what I just wrote, the trailer tells almost everything - and another (can't find) by some guy bashed ScarJo's "blank expression and limited range" which indicates he wasn't paying attention at all and to him I want to say: "Hey, Bub, she's not f*cking me either, but I'm not going to take it out on her in my reviews." Loser.
Score: 6/10 (bonus point for ScarJo's performance). Rent it.
BTW, the whole "we only use 10% of our brains" thing is total BS.
