Thanks to HBO On Demand, I have just started watching the HBO miniseries Rome.
It's great. I like the acting, the plots, the pace, the set design, the costumes. Is it accurate? It appears to be. But then, my knowledge is mainly from a mix of I, Claudius (book and DVD), The Roman Mysteries by Caroline Lawrence, and The Grass Crown (and sequels) by Colleen McCullough.
