Non-linear narratives essay

So I received my essay questions today and chose to do one: Telling a story in a non-linear way can enhance the experience for the audience/user. Discuss with reference to three media texts (either literature, film, television, radio, hypertext or video games). This is perfect to combine with my enjoyment of the current season of Lost, a non-linear text, I am going to write about its changing use of non-linear techniques and also the otehr aspects of the Lost universe as expressed with videogames and the internet. I don't care that I got a good mark with my own opinion in my last essay, this essay needs critical foundation and I need to spend a lot of time addressing the question directly and that needs theory and critical analysis.
