Well, as I said, the makers of the original approached it more as an animated
film. If they'd kept going in that vein as the technology caught up to their ambitions, they would've probably gone more in the direction of Pixar -- maybe done a sequel where, once the live-action characters entered the Grid, they became fully CGI creations.
Of course, that's what we're getting in Uprising
, a pure-cartoon version of the Grid, but I do wish it were more colorful and had some of the wild, exotic landscapes from the original's Sea of Simulation, instead of everything just being black and blue and red.
