Glad they chose British actors in the most important roles, as they are far better drama actors than Americans are. The history is interesting, so that coupled with good actors makes this series a pleasure to watch. Sure there's probably some inaccuracies, but that's usually how it is. There were some time skips back and forth, but not too many so it would be difficult to follow. And since the time skips to the before-days usually included Abe, it wasn't difficult to understand what timeline is going on. The makeup job on the actor who portayed Abraham could have been better, considering he was the only one they needed to masquarade one would have thought they could have went with top quality professionals like the people who transformed Colin in the BAtman.
