If you have seen the series Britannia, then this is way superior. I cannot believe it is all based on fact (pretty Viking maidens single-handedly fighting off scores of enemies...yeah right), but Britannia was so full of fake history you could almost call it science fiction - there is basis in fact here at least, as 8th Century AD Vikings pillage (though raping kept to a minimum no doubt to pander to modern pc sensibilities).
Some interesting characters in Floki and Athelstan especially, as the various clans and tribes are kept busy raiding and stealing and slaughtering each other.
It can be hard to differentiate characters and tell the leaders apart, so best watched in quick succession do viewers do not forget who is who.
Enjoyable stuff. But the 1950s VIKINGS movie which made Kirk Douglas a fortune and gave a break to Stanley Kubrick is probably more enjoyable as a short fix.
4 stars
