Query: BAD, BAD, BAD!

Do not waste your money on any of the Opera World series. I bought a VHS series of six Gilbert and Sullivan operettas, and I am SO sorry I wasted my money. I grew up on Gilbert and Sullivan (they were one of my mother's favorites) and these productions are a slap in the face to these two geniuses.
