Wolf Hall is fascinating, and I'd thoroughly recommend it (the books and the series), because it paints Cromwell in a modern light. He's basically written as a shrewd and competent Lawyer/Accountant. Maybe the sortof person who, in our time, could launch a successful business or be a partner in a law firm. But in that time, his skills are so unusual that he runs rings around almost everyone around him, and lays foundations that would shape the country for centuries to come. There's also a lot more to it than that, but the modern-ness of his skillset is very striking.
The books by Hillary Mantel that it's based on are even better (2 Booker prizes).
Her novel A Place of Greater Safety about the French Revolution is also really good.
I like Mantel too but I thought this novel (her first I think) was too long. Better in my mind are "Beyond Black" and "A Year in Ghazzah Street".
Yes, though also mentioned very early in this article as perhaps not the most accurate portrayal :)
Based on what the article says about Cromwell, most of Wolf Hall is roughly the same, apart from Cromwell's family background.
The only critique I can really find is that his father may not have been as violent as portrayed.
