A history lesson that's a little hard to keep up with. Well, with episodes lasting roughly 5 minutes, everything is quickfire learning. But you eventually get by. The very first scene in episode 1 got me interested and I was able to take in the fact that the series gives a human form to the countries of the world (Although at first I'd imagine England/Britain with darker hair, but I'm used to it now.)
Though I'm sure I'll get all sorts of disagreement, I actually prefer the FUNimation dub. I'm sorry, sub lovers. The accents put me in a good mood to watch. Maybe the narration seems to be dumbed down (Poland is a country! In Europe), but I think it's more of a humourous way.
The characterisation of the countries are... pretty much accurate enough.
