Wouldn't you still need to tweak light sources to get the scene to look 
"right"

Top of the line hardware is expensive. Having a renderer that can 
produce a usable image in minutes is not. One more thing to throw in 
(This isn't even raytraced, but scanline rendered) at this point, 
unbiased rendering is not practical for creating any 3D animated film, 
or even 3D special effects. The rendering tools they use in the movies 
produce excellent results, sometimes indistinguishable from the actual 
filmed portions.
