Saw the first one last night on Hannibal....wow bad history plus! There were good bits but they significantly blurred which Scipio's were involved and when and ignored great swathes of the key history like The Romans taking the battle to Spain before taking on Hannibal in Africa....a very distorted view of the 2nd Punic War. Based on this episode it doesn't look good but no doubt I will end up watching the others...but certainly no keeper!
If the first episode was on Hannibal, that belies the alleged theme of the series. Neither the Carthaginians nor the Romans were what any historian of the period would call 'barbarians'. Unless the episode is trying to say that the Carthaginians were civilized and faced a threat from a new group of barbarians, the Romans, who finally defeated them (hence, "Barbarians Rising"). But that would be very revisionist history.
