Designated Hero: Langdon in the end decides that Zobrist had the right idea and it won't be so bad if a third of the population is genetically altered against their will and becomes unfertile. This is more than a little jarring from someone who's supposed to be the hero, and who just spent (the first) 95% of the novelworking against and trying to stop the man portrayed as the villain.
Designated Villain: Zobrist. He manages to solve world overpopulation (although this theory has long since been debunked) without killing anyone (well, hardly anyone, and no one as a result of his virus). The only downside is that a large number of people won't be able to make new biological kids, but nothing is stopping them from adopting the countless preexisting children who don't have homes. Although he achieved all this by, ya know, genetically modifying a third of the world's populationwithout their consent.
Home Grown Hero: The entire Robert Langdon series note except The Lost Symbol, in/about which Dan Brown states in the foreword that he deliberately chose to wrote a novel set in his own homeland United States since fascinating art and history isn't only found in Europe—thus defying the trope can be summed up as 'an American scholar runs around Europe and uncovers Ancient Conspiracies left and right'.
Complete Monster: Christoph Bouchard is a Rogue Agent seeking the titular bioweapon to sell to the highest bidder. Tricking Professor Robert Langdon into his company, Bouchard is revealed to be fully aware Inferno has the capacity to wipe out half the world's population. Revealing his own misanthropic philosophy, Bouchard boasts to Langdon how Inferno will both make him rich and allow him to watch his hated humanity face doomsday.
Just Here for Godzilla: Many Emerald City fans only watch the movie to see Ana Ularu in a different role. Context Ularu's character, Mistress West, is regarded by fans to be one of, if not the, best character on the show.
Magnificent Bitch: Dr. Sienna Brooks was a highly-praised child prodigy and later became the girlfriend of college professor-turned-extremist Bertrand Zobrist. Believing in Zobrist's plan to unleash the "Inferno" virus designed to wipe out half of the world's population and thus, save humanity, Sienna picks up on seeing his plan through after he dies. Sienna arranges for Robert Langdon to be drugged and circumstances manipulated to believe he's in danger and that she's rescued him in order to gain his trust. She then continues to play his ally while he searches through clues left behind and saves him from the same "assassin" when actually sent to kill him for real later on. Upon discovering the location of the virus, Sienna abandons Langdon while thanking him for his part in the plan. Sienna then arranges to have the bag the virus is in set free through two explosive charges, kills Harry "The Provost" Sims when he tries to stop it and then kills herself to blow the charges, thus nearly guaranteeing the success of the plan.
They Changed It, Now It Sucks!: A criticism the film gets is the opposite of the two before it: while those movies were too slow and heavy in the details and explanations, this movie's pacing and editing are both way too brisk to the point that it doesn't take its time to be able to give certain details the proper attention and focus and it loses the audience as a result of feeling incoherent to them.
