I had totally forgotten watching the first series, but it was some years ago. Thread from that time https://www.mumsnet.com/talk/telly_addicts/4709399-marie-antoinette-bbc2-thursdays-and-iplayer
As it seems I enjoyed it I will watch tonight.
(Warning for those who cant be bothered to read series 1 thread, they series makers are not that bothered about historial accuracies!)
