I would personally remove skade, no fault of the actress, I just think the show kinda hamfisted her in, tried to build her up in too little time, and it came off really really corny to me.
I would add Guthred to this list.
I liked Ubba alot and even though he was a bit of an amalgamation I thought the actor did quite well, he made Ubba hilarious, intimidating and a bit "off" all at the same time.
Uhtred is..he is alright. Great actor, just seems a bit, i dunno, too handsome for the role?I
Im definitely on the book side of the non debate and while I certainly have issues with some directions of the show in season 3 I do enjoy it amd am over the moon with having a show based in my second favorite historical era.
Now if we could just get some sub roman britan show I would be ecstatic...hint hint BC.
