husband & I have been watching it, when we can stay awake! It's been on late on free-to-air here in Sydney, it finished last week (with Caesar's death). I think we fell asleep before then. But we were really enjoying it - well cast, well acted. husband was also very emphatic that Cleopatra was very well cast - according to history she was small with a boyish figure (Calpurnia's and Octavia's repeated insult to her) - no great beauty, but a political brain that was her main attraction.
husband & I are both interested in ancient history, husband especially is an expert on Republican and early Imperial Rome. My knowledge is more of Imperial Rome.
If you enjoyed this, try and find a British TV series from the mid-70s, called "I, Claudius." It is based on the books by British historian Robert Graves and had an amazing cast. Patrick Stewart in a minor role (Sejanus). John Hurt as an especially nasty and frightening Caligula and Derek Jacobi as Claudius (brilliantly acted, playing Claudius from a teenager to his death in his 80s).
Unlike "Rome", "I, Claudius" gives more detail of the women and their nastiness too, especially Livia (married to Augustus).
We bought the set on DVD. It's also bloodthirsty in places, but possibly less graphic (although the history is sufficiently nasty to make unavoidable some level of detail).
I think "Rome" is a British production too - they do historical drama very well indeed. But it does mean that some of the language, geared to British audiences, may be stronger than you're used to while it won't seem as strong to us in Australia or those in Britain. It IS stronger language than they used in "I, Claudius".
All in all, good stuff.
