- Angst? What Angst?: Del Rio takes all the crazy stuff that keeps happening around Lucy remarkably in stride, and he also never displays any real concern for all the collateral damage she leaves in her wake. Being a cop, it would've been his duty to at least try and stop her car rampage through the Paris rush hour, or check on his colleagues after she knocked them all out with a thought, but instead he just follows her around like a puppy. Not even all his office buddies getting killed off in the hospital fazes him. This guy either has a serious Lack of Empathy or a serious shock.
- Anvilicious: The entire opening sequence in regards to Lucy's impending doom, with the unsubtle cutaways to a mousetrap and an antelope being stalked by cheetahs as Lucy is entrapped.
- Big-Lipped Alligator Moment: Most of the exposition-cutaways to ideas and concepts being explained through animals (and occasionally people).
- Complete Monster: Mr. Jang is a Korean mob boss and drug kingpin. At the beginning of the film, he has Lucy's boyfriend shot and killed to take his drugs, the experimental CPH4. After having finished personally torturing two people to death, he forces Lucy and three others to become drug mules by sewing the bags of CPH4 into their abdomens so they can smuggle it to Europe under threat of having their families killed. When Lucy gains superpowers and confronts Jang to get the rest of the drugs she needs, he orders the other mules killed to extract his cargo and has his men kill numerous bystanders and cops who get in the way. When Lucy is close to achieving godhood, he collects what remains of his gang and storms the university building where Lucy's ascension is taking place, killing several more cops (and innocent bystanders) so he can murder Lucy himself.
- Hilarious in Hindsight:
- "Holy Shit!" Quotient: Lucy's super-powers, her increasingly bizarre dialogue, and the Going Cosmic Mental Time Travel at the end push the quotient to really high levels.
- Memetic Mutation: "What if we used 100% of the brain?"
- MST3K Mantra: Invoked by Besson concerning the 10% of their brain myth and other inconsistencies:Besson: It's not true. The good thing with movies is that you mix up everything and then in the end it looks real.
- Narm: There are several points in the movie which are possibly meant to be treated seriously but come off as humorous. Highlights include Mr. Jang's henchmen in the beginning using riot shields to shield themselves when they believe that Lucy's cargo could be a bomb (though that may have been done to be intentionally funny) and Lucy's foe-tossing walk.
- Paranoia Fuel: By the end, Lucy has become all of existence. So now she's able to warp reality whenever she feels like it! Creepy...
- Spiritual Adaptation:
- There is a substantial contingent of people who believe this might be the closest we'll ever get to a Black Widow movie, and seeing the parallels to Deathstroke as well. To add insult to injury, Marvel refused to do a Black Widow movie until six years after Lucy because they believed that action movies with a lead female don't do so well at the box-office. Lucy has become one of the highest grossing films for the summer of 2014.
- Considering how the actual AKIRA live-action adaptation is going, this might be the closest we ever get to it!
- Tear Jerker: The phone call Lucy has with her mother at the hospital. It's likely the last time she'll ever get to speak to her.
- They Wasted a Perfectly Good Plot
- The Taiwanese gangsters were using three other mules to smuggle their drugs (apart from Lucy of course)... If even one of them had gotten their bag ruptured like hers did, this movie could have had an evil antagonist that would give Lucy an actual run for her money. Nothing of the sort happens, and two of them are unceremoniously killed off when the gangsters come to collect their product.
- The drug CPH4 has been implied to be circulating around in the black market for a while, which leads to the possibility of other users of the drug developing supernatural abilities similar to Lucy's. This is never brought up in the movie.
- Unfortunate Implications: In one scene, Lucy shoots a perfectly innocent Taiwanese taxi driver, for no other reason than because he doesn't speak English while she's in an Asian country. Many people have called the film out on this. It seems somebody realized the problem, as the man after being shot is heard saying "Ow, my leg!" to indicate she didn't kill him, which was clearly dubbed in after the fact.
YMMV / Lucy
