It's not really a period drama so much as a costume drama- It's got a magical, Dickensian feel with the Victorian inspired costumes and settings. The world is located on the back of four elephants who are on a giant turtle…I haven't read any of the series but from what I've read about it and from watching this adaptation, it's a comical cross between Dickens and fantasy.

This series definitely made me interested in Terry Pratchett's works! Don't know if I'll have time to read them any time soon but one day it would be fun! I think if you like fantasy series like Harry Potter and such as well as costume dramas you should like this show.
