Frontal lobe: I'm far too cynical about these sorts of films now. Just tick a bunch of boxes on a sheet - robots, girls, guns, katanas - toss it into a blender and try and hold it together with whatever flimsy script you can concoct. It's hard to view a trailer like this and give the makers the benefit of the doubt. I predict a film composed of numerous flashy set-pieces that exist for no valid reason story-wise.
Hypothalmus: Hurr. Pretty girls in their underpants... Fiery explosions! Big guns are cool! I like robots! Boobies!
