Well, actually, when Don Bluth was hired on by 
Fox Animation to run it a few years back, he and 
his team had to totally relearn animation using 
the digital tools.  Don said he wasnt sure about 
it at first.  With cels and paint, you have 
somewhat more control over what you are going to 
get.  Digital has a lot of wierdness that comes 
with it.  Colors are off a lot of times, 
crashing, corruption, it's all there.  I have 
done traditional animation, and digital 
animation.  Both have strong points, and bad 
points.  But, if you look at films like American 
Tale,which was all hand done, and Titan A.E. 
which was all digitaly done, Titan just looses 
something with the digital.  Computers are 
extrememly handy in doing stuff, but, it all 
depends on the user.  I hope, for the sake of 
art, that everyone doesnt totally give up on the 
old way.
