Typically, when a series takes place at a supernatural boarding school, seriousness goes out the window. This is the case for "Legacies," which depicts classrooms full of students learning magic and engaging in an altered game of Quidditch called Wickery in the first episode. Danielle Rose Russell observed that while she loved doing the series, it was a far cry from the darker tone of the previous series.

"Filming 'The Originals' felt a bit more sophisticated. The cast was older, the material was different," Russell told Glitter. "'Legacies' is a fun, goofy show that has a totally different vibe." The vibe in question differs even from "The Vampire Diaries," which was also quite high school oriented. However, in the original series, for every love triangle or romantic proclamation, there was also real horror. Elena Gilbert (Nina Dobrev) is constantly hunted for her doppelgänger blood and is seconds away from death at any given moment. Additionally, secrecy is paramount in Mystic Falls, as the town is largely in the dark about vampires and other supernatural forces.

"Legacies" has the luxury of not being beholden to those restrictions. In the safety of the Salvatore School, teenagers are free to be kids and regularly flaunt their abilities. The concept of the series leans into teen shenanigans, despite its roots in gothic lore.
