An excellent interpretation of events in the lives of the Borgias. Of course, it is impossible to know how things truly happened, but there are good historical accounts, which seem to have been taken into consideration in the writing. The costuming is exquisite, and it would be hard to ask for a better story.
Rodrigo Borgia, as Pope Alexander, is shown as the wily fox he must have been. Lucezia is shown in a more sympathetic light than historians traditionally give her. Her portrayal is very realistic, and her bizarre relationships with those closest to her are such that the reactions she has to events in the series are entirely believable. Her brothers, Juan, Joffre, and lastly, Cesare, are well cast and very believable, as well -- particularly Cesare. His encounters with Machiavelli are extremely well done.
