The first season of Britannia eventually won me over, once I'd grown accustomed to its anachronistic style. This second season is a little more restrained, though not much, and I actually think it's a little less interesting for it. . But I'd still be up for a third season (and the way this second season leaves it, there's lot left to explore).
After a two year time jump, Aulis (David Morrissey) has established a more permanent camp in England and is awaiting the arrival of Emperor Claudius for an inspection. However, his duties to Rome have been replaced by his faith in a darker power and he's using his legions to slaughter young women searching for the prophesised savour. Said saviour, Cait (Eleanor Worthington-Cox) is still undertaking her training though, with wayward druid Divis (Nikolaj Lie Kaas) in another part of the country. All their plans though may be undone by the re-emergence of Veran's (Mackenzie Crook) brother Harka (Mackenzie Crook) who has ideas of his own.
There is a lot more focus to this season than the first. Gone is the political machinations as the Romans play the tribes against each other, instead this is the will of the two brothers and all about whether Cait can be knocked from her supposed destiny. There's still a lot of humour in this series though, particularly again with the double act of Divis and Cait, if nothing else comes from "Britannia" Nikolaj Lie Kaas should be elevated to starring roles. But in general performances, effects and script are all of a high standard (once you accept them for what they are).
My criticism of this series is that it turns out to be fairly inconsequential to the overall story. Very little is different at its conclusion than at its start, just that some of the characters are a bit more committed to their ideology. I suppose this is only really an issue depending on how much longer the show runs and whether we're actually going to see any of the fightback against the rule of Rome.
A third season isn't confirmed as I write my review but as I said previously, I'd watch more.
