I cringed when there was apparently a baignoire (bathtub) in the hallway of the Opera (I think they meant "toilet".) A chimney hadn't been cleaned in over 100 years, and a main character, who is supposed to be a great dancer, was able to pass as an Amish girl! (The Amish absolutely don't dance.) One of the elite dancers is even "self taught". (Real dancers will get a real kick out of that one.)
The show is rife with this kind of obvious misstep that could have been overcome with a little budget directed to even one well-rounded cultural consultant.
But if you can overlook the sometimes distractingly glaring errors, and you can go into a brainless entertainment zone and enjoy some frivolous fun, then this show may be for you. I had a hard time doing that (while watching every episode :-))
