Oh man!

That episode was awesome.
Can't say I'm a fan of him killing people left and right like that (the first one losing his fingers was good, they should have let him kick the others off the walls etc.) but the whole battle was fun to look at.
I like how the battles are being pictured in this show.
The armor, the weapons, the shields. It fits so well.
I also like how the Vikings look so unique and that they go all the way to show that in every scene. They aren't in uniform, each and everyone wears whatever he owns.
