I really enjoy Manu Bennett on this show. The young male lead grew on me. I liked the Rover woman from the start. The Elf Amberly was pretty flat. I'll be watching season 2 (and hoping they leave Amberly in that tree).
I thought a lot of the cast were pretty weak in terms of acting performances, I've liked Man Bennett since he was on Spartacus but he did seem like a slightly odd casting choice to me at first for his role as a druid.
I read the first few books just after I finished high school which was a while ago now so I don't remember if Amberly stays in the tree or not but either way her performance couldn't get more wooden
Funny thing though, I had no memory of the stories being set on a post apocalyptic earth so that was a bit of a surprise but a lot of time has passed since I read them.
I'm interested enough to see what they do with season 2.
