When it was first announced that this series started production in 2019 there was demand for this series in the Netherlands. It is possible that the residents of the Netherlands thought this series was going to be a sequel to the series under the same name which originally aired in the United States between 1991 and 1994. Around 2005 the 1991-1994 series was aired daily in the late afternoon in the Netherlands. The ratings that were achieved in the late afternoon were a custom to achieve in the early evening which means the 1991-1994 series was quite a success in the Netherlands around 2005.
