He’s a much less active character here than he’s a reactive character, which makes his declaration that he’s a “criminal mastermind” in the film’s final moments a bit strange.
In Eoin Colfer’s novel, Artemis Fowl is basically a miniature Bond villain.
He’s extremely smart and cunning, meticulously laying out his plans for personal fortune, and he adopts a cold, ruthless demeanor.
In the movie, however, the title character (Ferdia Shaw) is notably less nefarious.
