The title of the series, The Borgia's - the complete series one, holds the promise of at least one other season to come; I for one, welcome the continuation of this series.
I found the story engaging, the acting superb and the period costumes and settings, engrossing.
Given the historical record represented, one wonder how the Catholic church ever survived. While this is only the story of the Borgia's, several other Bishops of Rome, over the centuries, were just as loose in keeping faith with God's 10 commandments.
In my opinion, this is excellent viewing, very graphic in areas, not for the squeamish, or those that are shocked by open sexuality; the series is definitely meant for a mature audience.
