Belgravia: The Next Chapter

Belgravia was written by Julian Fellow and his attention to details was visible everywhere. It wasn't perfect, but it was interesting, the actors were good, the time period well presented. But this New Chapter feels like a high school play. The actor playing Frédéric Trenchard is so bad! The costumes are awful, again it looks like a mom took whatever look like from before 1900 and dressed the characters with it, with no research of the specific period. So there is costume from the Elizabethan period (16th century) mixed with the early Victorian (1840'). The characters display 21st century values and attitude. It could be funny if it was a spoof but it's not supposed to be. Neither is it a period-fantasty like Bridgerton. I can't understand how Julian Fellow accepted to have is name associated to it. Did he lost a bet?
