Luc Besson and I haven’t had the best relationship since I started reviewing movies for The Sunflower. My first review assignment here was for “The Family,” which was entirely forgettable and uninteresting. He also produced one of the worst movies I’ve seen in years, “Brick Mansions.”

Unfortunately, he’s back in the director’s chair again with “Lucy,” an impressively stupid Scarlett Johansson thriller about what would happen if someone could use more than 10 percent of their brain. The main criticism of the film before its release was that there’s no scientific proof behind the whole “10 percent of your brain” thing, but since chimpanzees can’t emulate human speech either, I was willing to put that aside and just enjoy the ride.

Besson couldn’t even give me that. The barebones plot doesn’t make a lot of sense, as our titular protagonist has a bag of magical blue powder surgically inserted into her intestines by some high-end drug lords against her will, as that’s part of their smuggling operation for some reason. The bag leaks into her bloodstream, though, and Lucy’s brain becomes increasingly powerful over the course of the film’s meager 90-minute runtime.

If most of the movie had been Lucy using wacky brain powers to take out hordes of incompetent male goons, that probably would’ve been decent, light entertainment. Oddly enough, however, that makes up less than a quarter of the story. She spends the rest of it spouting incomprehensible dialogue about the true nature of existence.

The most damning part of “Lucy” is the character herself, really. Women who are much smarter than I am have certainly said this better than I can, but there’s an obnoxious male idea of the “strong female character” that usually manifests in pop culture as a “badass” woman with no emotions or personality to speak of.

When Lucy’s cognitive functions are enhanced, she becomes selfish and bland. Simply put, she’s just an unlikable character.

She’s also a bit of a racist apparently, as (I didn’t take an exact headcount, so this is a rough estimate) every person she kills is nonwhite. Near the beginning, she shoots a Taiwanese cab driver in the leg because he doesn’t speak English. Not long after that, she murders another innocent Taiwanese person on an operating table in a hospital just so she can force the doctors to find out what’s wrong with her. These moments are literally as brief as a gunshot, but they’re so morally abhorrent that they stuck with me over everything else in the movie.

With such a brief runtime, the nicest thing I can say about “Lucy” is that it won’t waste too much of your time. It’s so utterly (and ironically) brainless that, by the time she achieved 100 percent brainpower and was zooming through Windows Media Player visualizers, all I could do was laugh. They might have been onto something if the whole movie had been like that, but as it is, I can’t recommend “Lucy” to anyone.
