When you get into any kind of period work, or any kind of prosthetic work, or anything that alters what your 8×10 looks like, it's the joy of escaping and becoming somebody else. And it is definitely freeing.
I hope to read a Harry Potter novel soon, to see what it's all about. I admit to being annoyed that many good light fantasy writers have had trouble getting published, in England and elsewhere, when it is obvious the readers were waiting for us all along.
