I disagree with you there, the art for the characters is simple and subtle, yet each character is unique and is different by more than simply a hair color. The amount of effort that went into creating those characters is much more than it appears.
The backgrounds though, are more than "extremely undetailed" or "smooth gradient", THERE IS THAT EXACT SAME MOUNTAIN AREA IN 5 DIFFERENT PLACES WITH THE COLOR GRANDIENTS AND FOG SLIGHTLY CHANGED. THEY THEN SPEND OVER A SOLID MINUTE PANNING OVER IT AS IF THE ANIMATORS DON'T REALIZE THAT WE CAN TELL THEY ARE BEING LAZY. THEY THEN DO IT AGAIN AND AGAIN.
In any case, it's been several years, and let's hope the improvements in production and more experience in the staff and directors make for a positive impact on the new 720p mushishi. Don't be too hard on the new series and judge it by it's predecessor's mistakes.
