The thing is, is this better or worse than seeing
"We obviously haven't serviced our copying machine
in years"-lines or "We filmed this is a dust
storm"-artifacts when doing zoom-ins? 

Of course, that just comes down to a matter of
aesthetics ^_^.

Sure, not all cel art is that bad, but hopefully
not all digital art will be grainy.

Like I said, CG can be used for good or for
evil...
