I don't think anyone is attempting a blow-by-blow in the literary equivalent of Gus Van Sant's Psycho 2.0. Furthermore, I think your assessment is a bit unfair. You haven't read Nabokov's Lolita? Your bad. That doesn't mean other people can't be inspired by or riff on the material of their betters in creating new works. That and I'm still not sure why age matters in artistic endeavors. If someone is talented, has a fresh perspective, and a workable contextual grounding, why does it matter how old they are?

Starred Review. Pessl's stunning debut is an elaborate construction modeled after the syllabus of a college literature course—36 chapters are named after everything from Othello to Paradise Lost to The Big Sleep—that culminates with a final exam. It comes as no surprise, then, that teen narrator Blue Van Meer, the daughter of an itinerant academic, has an impressive vocabulary and a knack for esoteric citation that makes Salinger's Seymour Glass look like a dunce. Following the mysterious death of her butterfly-obsessed mother, Blue and her father, Gareth, embark, in another nod to Nabokov, on a tour of picturesque college towns, never staying anyplace longer than a semester. This doesn't bode well for Blue's social life, but when the Van Meers settle in Stockton, N.C., for the entirety of Blue's senior year, she befriends—sort of—a group of eccentric geniuses (referred to by their classmates as the Bluebloods) and their ringleader, film studies teacher Hannah Schneider. As Blue becomes enmeshed with Hannah and the Bluebloods, the novel becomes a murder mystery so intricately plotted that, after absorbing the late-chapter revelations, readers will be tempted to start again at the beginning in order to watch the tiny clues fall into place. Like its intriguing main characters, this novel is many things at once—it's a campy, knowing take on the themes that made The Secret History and Prep such massive bestsellers, a wry sendup of most of the Western canon and, most importantly, a sincere and uniquely twisted look at love, coming of age and identity.

I'd hardly call a few similarities enough to garner the title of "remake".

I'm sorry, I really don't mean this to be an attack. I was just bothered by the assumption that somehow being young means one is incapable of contributing anything worthwhile in terms of culture.
