Last week we took the whole family (2 kids included) to see "Flushed Away" from Aardman... Wow. Great writing, excellent animation. It was really neat to see how they have transitioned from stop-motion to CG animation, but kept the look and style they are associated with. ILM tried to duplicate stop-motion in "Mars Attacks" but it wasn't that great. Aardman hit the nail on the head with "Flushed Away," which looks just plain good. But of course, I can only imagine has simplified things in many regards (all that water? no fun with stop-motion).
I'm hoping the DVD will have some extras that'll explain more :)
