I've never read Dorothy - Return to Oz, but I've heard from pretty much everyone who has that it's bad. And yeah, the characters getting old and dying makes no sense, even if death and aging were restored in Oz. I mean, the Lion, sure, since they don't live that long in our world. But how could the Scarecrow die? You would think that his clothes would wear out, though, since they were already pretty worn at the time he was made. But maybe they're replaced a little at a time, like when the Sawhorse loses a limb and a newly-made one automatically works.

I read Something Wicked This Way Comes in the ninth grade, but I don't remember too much about it, other than the carousel that can make people older or younger. And I haven't read any of the Worst Witch books, but I DID see the movie from the eighties, which has Tim Curry singing a song about how your dog could turn into a cat on Halloween.
