GOT: A Waste of Ian McShane

I really do not understand the logic of bringing in an actor like Ian McShane for one episode on Game of Thrones. It was a treat, but also a waste that did not move the story forward. And what the hell were they building?

Here is McShane on his role as Brother Ray:

 ...he's an ex warrior who’s grown tired of the murdering life and trying to lead another kind of life.

Okay, but more story development would have been nice. So it goes with this show where the characters die like flies.

The good news is that during this same interview McShane noted he should be appearing at some point in a Deadwood film. That too would be quite a treat.
