Good start (No spoilers)
19 February 2016 | by ddiesonneSee all my reviews

Quite a few surprising decisions taken by the main characters in this episode, some of them creating dismay, others satisfaction, but in the end, all helping shape up their future paths.

It's a really good season start, even the single fight scene of this episode, seem to be improved considerably.

Overall, the show gets even more captivating as the plot divides into even more parts, focused on different locations and characters. Now besides the old Ragnar's path, there's also a Bjorn's one, Rollo's, Lagertha's, Aslaug's, Floki's... Even the English part, even though it's completely missing from this episode, won't be left aside (as presented by the end-episode teasers). In other words, the show's plot have become a lot more intricate than one could've foreseen two seasons ago. And that's not a bad thing at all.

Furthermmore, there are a couple of scenes that will surely be appreciated by those interested in history and historical accuracies. Some of them will probably create some debates, but in the end, Vikings cares to remind us that it's a historical show after all, and that's perfectly fine by me.
