There's quite a slew of animation being released nowadays, whether movies or TV, in order to fill up available room for programming.
But especially with movies, we've seen a shift from animated releases up through the 80's, to movies in the 90's where celebrities began to be selected as cast leads in animated features, as opposed to trained voice actors whose entire career has been spent voicing characters rather than playing them in live-action pictures. (Writer Scott Meslow recently in Atlantic Mag stated the turning point occurred with Robin Williams' performance in Disney's Aladdin.)
Do you think overall this is a positive trend or a negative one? Why or why not? Does live-action acting carry over to voice acting or not? Who would you consider to be versatile enough to function effectively in live-action as well as animated features?
