i just came into it several episodes back...this is the 2nd season. the first seasons DVD is available. it's definitely the kind of show you can get into, if you find the subject of ancient rome interesting (and i bet y'all do). however, i can't help but compare it to classics of film like Cleopatra (Liz Taylor, Richard Burton, Rex Harrison, Roddy McDowall, et al.). it will, naturally, come up short in such comparisons because the acting and the dialogue aren't stellar, but it's good enough to enjoy. and if you're like me, you can get into almost anything, once you've watched enough to have a sense of the story, characters, etc.
at this point, julius caesar has been murdered, which of course is rather important, and several episodes' worth of stuff has happened since then.
new episodes of season 2 air on HBO every sunday night at 9pm.
