I watched it (still have to finish it actually). It's pretty entertaining and it's nice to see the History Channel getting back to shows that are actually about history, but I miss Ed Herrmann's narration.
As for the version you get, I think it's pretty honest. Of course it's told from an American perspective and is a little biased in that regard, but it's not inaccurate. I don't think it's on the level of The Presidents series, but it's entertaining.
