It is more irritating to me when an animated character gets a new voice actor, than when a live action actor is recast. I can adjust to changes made, but when a new actor is cast, it gives me sense of disconnecting from the character some way that I can not really explain. For me Rob Low does not seem to fit Simba, I will of course get used to it.

I heard that Matthew Broadrick doesn't want to work with Disney anymore. Also, it's kinda hard to get original actors to come back for more because of cost, AND the fact that their most likely doing or working on something else.
