In the movie Nicholas and Alexandra, I was kind of disappointed how few times OTMA actually had a part, especially the part about who I suppose was supposed to be Tatiana! Ugh! She would never do such a random and inappropriate thing!
Also, when Nicholas "blames" Alix that it was her fault Alexsy had haemophillia! He would never do that to his dear Alix, he loved her very much.
Sorry if I'm being too opinionated! That's just what I think.
