The cape is probably due to him being the Necromonger Lord Marshall or whatever, yeah?
Riddick series has been great. I loved Pitch Black, and Chronicles reminded me of a sort of sci-fi Conan saga, the way it played out. I really enjoyed the art direction and the attempts at doing something a tiny, eeny weeny bit original by the production team.
Riddick is a bit of a cornish ball of character, but I like him anyway. He has fun little moments where he doesnt have to act all billy badass
I like those.
