Oh, god. Gainax spent so much leading up to the big battle of episode six that they didn't have enough money to animate it. So they gray scaled the entire episode and shot the pencil tests for the final battle as a montage hoping nobody would notice. You want to see over ambition wreck a show? I mean, how the hell were they supposed to film that madness and come in under time and budget restraints? They had easily twenty more minutes of material that they smooshed into like three.
