As I've already said on the Windsor thread about this series The Lost Prince, why were the Romanovs even in it at all, let alone their gruesome death scene - quite unnecessary.
Prince John would have barely met Nicholas, Alexandra and their children so I don't understand this.
I realise that some indirect characters have to be included at times to provide an historical backdrop etc., but the focus should have been far more on Prince John's parents, brothers and sister, grandparents etc., how they related to him and how they coped with his disabilities.
The Romanovs? Totally irrelevant here. Their inclusion spoilt it for me.
