This is billed as a "psychological thriller", and was first released at the Sundance Film Festival in 2001. While this is certainly not "mainstream" science fiction, and probably many would not even dare to classify it as science fiction, I would argue that Donnie Darko IS science fiction. The setting is a suburban community in the 1980's and the protagonist is a trouble teenager trying to figure out the strange things thare shape his life. The teenage life is well written, unlike most movies with main characters in that age group. The science fiction centers around the idea of time travel. <what is is with the time travel theme of late? I can't escape it> There's a great section about a kooky old woman, once a nun, who disowned her faith and wrote a book called "The philosophy of Time Travel". Most of the movie is surreal, with Donnie being haunted by a demented rabbit.

In summation: Definately a movie to check out if your in the mood for something offbeat.
