First of all, computer animation is certainly a tremendous and viable medium today. But the warmth and personality derived from 2-D animation, in my opinion, cannot be surpassed. Certain stories lend themselves well to 3-D animation and I won't labor this with naming them, but in my bones, I still respond more emotionally to the artists feel in 2-D. You feel the 'actor' in the animator more personally...it's hard to explain.
