I had resisted âThe Spanish Princessâ for as long as I could, believing it to be another historical drama with all the charm of a soap and the kind of attention to historical accuracy that has the same effect as a fingernail on a blackboard to a history buff. In short, I was convinced that it would show itself to be like âThe Reign,â that marvel of production by the CW about Mary Stuartâs (the future Mary Queen of Scots) early years in France â with what looks to be a casting call for âBring It On.â Historical dramas must necessarily play with facts and make up dialogue to be entertaining. Weâre lucky to find a modicum of historical accuracy in any of them.
