The Animatrix
The Animatrix was an interesting attempt to expand on the original film but for me most of the animations didn't add much. However one animation stood out from the crowd and, as a software engineer, seemed perfect. In Beyond we visit a haunted house called by a flaw in the matrixes programming. Here the rules break down and those exploring the house are amazed and disturbed by what they find. This animation ignores mysticism so prevalent in the other films and shows, with an nice tale, what a detailed simulation like the matrix might be like on the inside.
