Revolutions Hell
Is it me or was Revolutions abit, how shall I say it...Hell obsessed. Now I'm not saying that's a bad thing if there was something that they were trying to tell us or show us.
Take the Merovingian's club called Hel (which at first I thought was Sodom and Gommorah). Then Mifune's talk to the army of Zion "if we have to give our lives, we give them Hell before we do." And Zion's geographical location, near the Earth's core is where you might expect Hell to be, and when the machines had taked the dock Zion did look like Hell.
Even Roland said it to Neo onboard the Hammer, "believe me this ship will go to Hell long before I let you take it anywhere," while on their way to Zion.
So were they trying to tell us something, if so what?
