On balance, then, as a visualization of ancient Rome, "Rome" is certainly better than most of its genre, but lacks the dramatic tension of that classic series, "I, Claudius". We do not see here the political implausibilities of "Gladiator", but neither do we see a strictly accurate (or, in many instances, even convincing) portrayal of historical personalities. And as a dramatic series, "Rome" does not leave the viewer at the end of an episode eager to see what happens next. We already know.
Rome is showing in Britain right now and I've seen perhaps half of the episodes. The casting of the main characters is pretty good but, as usual with such things, the series makes a lot of stuff up.
