The proof that sex and violence is not needed.
My my, I think I've found the missing link of movies right here.
Every movie like this I find, I make a little interpritation, and this one gets a neat one, lemme think about it for a second.
*Spoiler of movie*
Ok,
The start where that city is, thats one of the lights, those little lights are worlds, and on the little lights are so many strange and mysterious objects and animate (opposed to inanimate) objects, though I'm not sure if they're living or not. The light that was making all those things move near the start of the movie, and illumenating everything represents a higher power, one that creates things and illuminates them. The fact that all the lights kept heading to the one bigger light signifies the highest power, that creates, and destroys the lower powers, and how everything must end, and how ironicly, you end where you start.
Now thats my interpritation... of course, thats just a interpritation.
