I know I'm probably late on this, since I haven't been able to read the boards lately, but since I'm still gay for Stannis, I've got to ask... What's the problem?
I thought the last episode and his part was awesomesauce. As a matter of fact, I haven't had a huge issue with any piece of Dillane's portrayal, and here at the culmination it seems even better. I've heard lots of shit talked by book readers, especially on wiki forums and comments on youtube vidyas, but I've yet to figure out, based on what the criticism has revolved around, who could do it better.
Near as I can tell he's a character with little amiable personality, utterly uncompromising, and largely unpleasant due to a weird combination of legal formality and crazy religion. I don't really see how another actor could do it better, but I hear it all the time that the series version of Stannis is far worse than the book iteration. Can someone explain this to me?
