I guess I ran out of space in my last post. Here's what else I was trying to say:
England was still climbing out of the Middle Ages during the reign of Henry VIII. So the English Renaissance didn't really begin until around the end of Elizabeth's reign (1558-1603). Shakespeare's first play was staged in the 1590s.
As for the portrayal of Elizabeth, except for when she tells Dudley that there's "one mistress and no master," I don't see much Elizabeth I in the movie. The movie Eliz. is indecisive unsure of herself. The real Eliz. was born a princess. She had the best education. She had people to open doors for her, dress her, even take punishment instead of her (there is a story that Katherine of Aragon didn't know how to turn a doorknob!). She was Henry VIII's daughter. I think she would have known how to rule.
The movie also makes it appear that Eliz. never married because she couldn't decide who to marry. Think about it. Her own mother was beheaded for not bearing a son, and she had four stepmothers by the time she was 14. She couldn't have had a good impression of marriage. Besides, before her sister Mary, England had never had a ruling queen. Even Mary went through a marriage with the king of Spain to secure her place on the throne. Elizabeth knew that whoever she married would eventually become king and take the power from her. She would not have anyone rule her!!
