1. The original inked-and-then-digitally-colored gritty look is gone, replaced with a sleek vector art style.
2. Everyone's been redesigned to look cuter and rounder
3. The color palette is now bright pink and blue instead of the original red, violet and olive.
4. The hyper-detailed, fisheye lens backgrounds of the past have been replaced with new ones that have a million color filters but lack the dark comic book style.
5. The animation is a little less fluid from what we've seen
6. Lots of other little things. Screens glow blue instead of magenta, the sky isn't red, the clouds are rounded, the shading isn't as dark, etc.
I'm ready to be wowed by a killer script to distract from the jarring differences in the visuals.
