This is a fun film. Made on a limited budget, especially for a period piece, the 19th century world is thoroughly recreated; and, none of the seams are showing. It is, of course, a movie; and, not a documentary. Some of the events (and, people) are not intended to be historical. But, it's still a lot of fun.
The movie hints that the real "Hysteria" plaguing society, and health care, could be cured, with a little ingenuity and investment; while the wealthy waste enormous amounts of money, indulging themselves, creating their own health problems. At least, it suggests that this was true during the Victorian Era; whether, that's still true, in the 21st century, is beyond the scope of this film comedy.
