If you know nothing about Spanish or English history of this era, this may be fun for you. But there are so many historical inconsistencies that to me it was sometimes annoying. Nice costumes though!
In spite of that said, the series is very watchable and easy to enjoy. The liberties taken with what is actually known of the story of Katherine of Aragon could possibly be justified or even possible. As the saying goes, history is written by the winners.
