The British

The special effects are fine, the re-enactments are fine. But when interviewing people, they have only 2 or 3 historians in episode 1, and the rest is a bunch of random actors, broadcasters and other such people without any credentials to talk about history.

They also cherry-picked events arbitrarily. How come they have an episode about the celts and the romans and forget all about Caesar and Boudicca? Episode 1 covers the 400 years or so of roman ocupation, and then episode 2 brushes through saxon times, the viking age and the normans, so in episode 3 they can talk about Tudors.

I mean, come on! This is just being lazy. There's a massive amount of history in there and they just couldn't be bothered. It had a lot of wasted potential. Pity.
