Vinland Saga's second season retains the beautiful visuals from the first and still contrasts those with the cruel nature of the world it portrays. However, the tone and overall nature of the show have changed significantly. For most of the season the setting has been changed from the battlefield to just the field. The season has little action and has become much more drama oriented.
While the lack of action may be a turn off for some viewers, my problem with the second season lies elsewhere: I'm old enough to have gotten most youthful idealism out of my system, so I simply dont reasonate with the now turned pacifist protagonist. The show goes from amazinly writen to silly as soon as pacifist Thorfinn enters the fray, making the tone oddly inconsistent.
All that being said, the show has good production value and, when not disturbed by Thorfinn's pacifism, can be quite gripping.
In conclusion, if you go into this season expecting action and a "badass" protagonist, you are going to be disapointed. But if you are looking for a gripping drama, and are not put off by the idea of viking Gandhi, this show is for you.
