I think I understand the ending to T3 a little better now.

Contrary to my last opinion of the T3-ending, I think it was actually done in the James Cameron-school of thought, though it might have resembled Tim Burton's Planet of the Apes a little too heaviliy (complete with the President of the United States emblem and everything). The overall moral of the Terminator movies rests in the anti-technology thought that machines will inevitably take over - thus, if the TX was destroyed and judgement day was stopped, it would have been retarded in a way; it gives an infinite plot-hole to continue the transport of terminators back to kill John Connor indefinitely.

This ending works better I guess, after I thought about it a little more. It ends pessimistically, with the world destroying itself, a victim of the machines it creates - hence, the moral of the film socialistically represents the old-school moral of the original Planet of the Apes: humans will fight each other until they destroy themselves. And it actually happens!

I know y'all probably think I'm analyzing Terminator too heavily, but James Cameron isn't a brainless director. His socialist thoughts permeate every film he makes, including Titanic, and Terminator is the archetype of his method of living out the hypothetical through the fantasy of cinema. At heart, Cameron is a pessimist, a cynic of capitalist technology that he uses Arnie to eradicate.

Goodnight.
