The Rave seen was shot in South Central LA. Maybe they were trying to save money on extras. Or, with everyone in zion breeding, perhaps it's just that the offspring would over the years become dominantly people of color. Then again, maybe they just thought it looked kewl.
Anyone have any thoughts on why Seraph wasn't in the first film, and why the Oracle needs protection in the second? Also, why is she interested in the human's cause? Why would she care about their conflict?
I find it funny that even after third viewings some people STILL are uncertain about key parts. Sorry but I prefer 1 viewing for comprehension of 99% of all films. The extra 1% I reserve for David Lynch, etc.
You are here because you think there is deeper meaning, and you want to figure things out. But have you considered that maybe the film is just a convoluted mess?
