If I were a film director, I would be sticking references to other films into my movies all over the place. They would be films I admired, mostly, which means that somewhere, sometime, I would probably put in a reference to Donnie Darko, a personal favorite. Now, imagine that somebody made a movie that was entirely Donnie Darko references. Would it be a sequel to Donnie Darko? A tribute? A fan fiction? Considering that S. Darko stars Daveigh Chase as the grown-up version of her D. Darko character, Samantha from Sparkle Motion, the movie is obviously trying to be a sequel, but the only thing that separates this from fan fiction is that somebody gave the director Briana Evigan, Ed Westwick and a lot of money and let him make it into a movie.
