This season is by far the weakest. The perfect example of wasted potential. I'm still only on episode 10 but I doubt the other 10 are any better.
Edit: Yup. Nice way to murder a series so great. Bjorn and Lagertha were completely massacred. Floki's journey doesn't really amount to his character in any way. Ivar was nice for the most part. This clearly needs to go back to the 10 episodes formula.
Absolutely amazing acting! Though I'm still in love with this concept of "why did it happened?" instead of "who did it?", the second season did the most cliche thing of not faring as well as the first. The mystery did unravel as well as the first season but it felt like every other story line over shone the kid's. Nevertheless, it's still not too bad and worth watching!
