I don't think I "like" Marie, per se. If I were a contemporary of hers, I probably would have seen her as "over the top" theatrical, dramatic, flamboyant, as some did. You've made good points about what a marriage to George V would probably have meant, and I concede that argument. : ) As a day-to-day person, I don't think she was all that likeable.
However...as a Queen, she knew just how to use what she had, and she was a quick study. In politics, at least, she stood behind Nando and bolstered him.
And, she did take beautiful photos. ; )
